Belief propagation (BP) decoding has been recognized for its capacity-approaching performance and high throughput when decoding long low-density parity-check (LDPC) codes. However, the application of BP decoding for short codes is hindered by dense parity-check matrices (PCMs) and prevalent short cycles in the Tanner graph. In this paper, we introduce a general method to extract an optimized sparse PCM for short binary block codes, which removes length-four cycles and enhances the connectivity of short cycles to enable BP decoding with improved performance. Notably, for short binary codes with lengths up to 64, our BP decoding performance approaches the maximum likelihood bound and surpasses the best-reported BP results with reduced computational complexity. Compared with other universal decoding algorithms, BP decoding using our extracted sparse PCMs is competitive in terms of both error-rate performance and computational complexity. These promising results suggest that our method to improve BP decoding for short codes is a step toward a practical universal BP decoder for next-generation communication systems. © 1983-2012 IEEE.

In this paper, we propose a multi-user green probabilistic semantic communication (PSC) system for semantic communication (SemCom) facilitated by probabilistic knowledge graphs (PKGs), which are knowledge graphs (KGs) integrated with probability to represent semantic information. In the considered model, semantic information of different users is represented by PKGs. On this basis, we design a semantic compression model for multi-user downlink task-oriented SemCom, utilizing the semantic compression ratio (SCR) as a parameter to connect the computation and communication processes of information transmission. Utilizing rate-splitting multiple access (RSMA) technology, the transmitted messages are splitted into shared and private ones. Considering the limited wireless resources and constraint in semantic communication, an optimization problem with the goal of minimizing system energy consumption comprehensively considering the computation and communication process is formulated. In order to address the optimization problem, we propose an alternating optimization algorithm that tackles sub-problems of power allocation and beamforming design with successive convex approximation (SCA) method, semantic compression ratio optimization with variable substitution method, and computation capacity allocation with obtaining closed-form optimal solution. Simulation results verify the effectiveness of the proposed algorithm. © 2017 IEEE.

MPSoCs have been proposed as a promising architecture choice to overcome the challenging embedded electronics requirements, characterized by tights development times and fast evolution of applications. The MPSoC flexibility, also represents a system vulnerability. As security requirements vary dramatically for different applications, the challenge is to provide MPSoC security that allows a trustworthy system that meets all the security requirements of such applications. NoC has become an attractive alternative to support the MPSoC communication requirements. Our work proposes the implementation of dynamic security architecture to overcome present MPSoC vulnerabilities. We integrate agile and dynamic security firewalls into the NoC in order to detect attacks based on different security rules. We evaluate the effectiveness of our approach over several MPSoCs scenarios and estimate their impact on the overall performance. We show that our architecture can perform a fast detection of a wide range of attacks and a fast configuration of the different security policies for several MPSoC applications. © 2011 ACM.

In this paper, the radar clutter reconstruction model based on singularity power spectrum (SPS) and instantaneous singularity exponent (ISE) is proposed. The proposed ISE-SPS model consists of power measure channel and dimension measure channel. The multi-scale wavelet coefficients are estimated based on the coupling of the two channels to reconstruct the radar sea clutter. Experiment based on the Ice Multi-parameter Imaging X-Band (IPIX) indicates that the proposed model behaves better than the N-partitioned random multiplicative model (NRMM), with about 32% increment in terms of correlation coefficient and normalized MSE of MFS and SPS. © 2020 IEEE.

MPSoCs are able to support multiple applications on the same chip. This flexibility offered by the MPSoC also represents a vulnerability, turning the MPSoC security specially challenging. The goal of the designers is to provide MPSoC protection that meets the performance and security requirements of all the applications. The Network-on-chip (NoC) interconnection structure can be used to efficiently overcome the present MPSoC vulnerabilities. In this paper, we present the implementation of a hierarchical security NoC-based architecture to detect and prevent a wide range of MPSoC attacks. We integrate agile and dynamic security firewalls into the NoC in order to detect attacks based on different security rules. It uses the QoSS (Quality of Security Service) concept. It takes into account the tradeoff between security and performance. We evaluate the effectiveness of our approach over several MPSoCs attack scenarios and estimate their impact on the overall performance. We show that our architecture can perform a fast detection of a wide range of attacks and a fast configuration of the different security policies for several MPSoC applications. © 2012 IEEE.

Three dimension Multi processors System-on-Chip (3D-MPSoCs) hold promises to allow the development of compact and efficient devices. They support many applications on the same die, able of being mapped dynamically during the execution time. Each application may have different communication requirements. Quality-of-Service (QoS) can be implemented at the communication structure (CS) to support the communication requirements of the dynamic 3D-MPSoC. Our work proposes QoS 3D-HoC, a new 3D-CS that implements the QoS. We evaluate the performance of our architecture over several 3D-MPSoC synthetic and real traffic scenarios and estimate their impact overall CS performance. We compare our architecture against the previous 3D-CS with and without QoS and show that our approach meets the communication requirements while reducing the latency and power up to 87% and 39%, respectively when compared to single 3D-NoC. © 2013 IEEE.

Through-Silicon-Vias (TSVs) are the key enabling technology for high performance of three-dimension Multi-processor System-on-Chip (3D-MPSoC). Physical weaknesses of TSVs can be exploited by malicious software to attack the system. By means of the manipulation of the TSV communication an attacker is able to modify, spy and even denial the TSV communication. Extending just 2D security mechanisms to 3D-MPSoC without taking into account the 3D aspects will not protect the system. In this paper we propose 3D-SECTSV, a flexible and efficient security architecture based on a 3D-NoC communication structure able to protect the TSV data exchange of 3D-MPSoCs. We compare our approach with several 3D-protection proposals, including the simple extension of 2D security countermeasures. We show that our solution outperforms other approaches with respect to attack detection while decreasing cost and performance impact on the system. © 2015 IEEE.

MPSoCs are able to support multiple applications on the same chip. This flexibility also represents a vulnerability, turning the MPSoC security specially challenging. Most of the current MPSoCs security services are based on symmetric and public-key cryptographic mechanisms. So that, MPSoCs integrate a large set of keys that must be exchanged in an efficient and secure way. In such scenario, any security concept will be ineffective if the key management is weak. In this paper, we present the implementation of an on-chip hybrid communication (HoCs) security-based architecture, that combines bus and Network-on-chip (NoC), to address the efficient and secure key management at MPSoCs. The HoC implements dynamically the QoSS (Quality of Security Service) concept that allows the customization of security. We evaluate the effectiveness of our approach over several MPSoCs attack scenarios and estimate their impact on the overall performance. We show that our architecture can perform a fast detection of a wide range of attacks and a fast configuration of the different security policies for several MPSoC applications. Our hybrid approach saves upto 16% and 25% of communication latency and power consumption, respectively, when compared to the NoC-based architecture without any security. ©2012 IEEE.

Multi-hop time synchronization in wireless sensor networks (WSNs) is often time-consuming and error-prone due to random time-stamp delays for MAC layer access and unstable clocks of intermediate nodes. Constructive interference (CI), a recently discovered physical layer phenomenon, allows multiple nodes transmit and forward an identical packet simultaneously. By leveraging CI, we propose direct multi-hop (DMH) time synchronization by directly utilizing the time-stamps from the sink node instead of intermediate nodes, which avoids the error caused by the unstable clock of intermediate nodes. DMH doesn't need decode the flooding time synchronization beacons. Moreover, DMH explores the linear regression technique in CI based time synchronization to counterbalance the clock drifts due to clock skews. © 2012 ACM.

With the increasement of frequency band and platform mobility, communication system faces more severe time-frequency double dispersion influence. Folded chirp-rate shift keying (FCrSK) modulation technique has been proposed to solve communication transmission problem in high dynamic doppler channel owe to its time-frequency shift invariance. However, it dose not consider some influence of time-frequency dual selective channel (TDSC). In this paper, spectrum structure of FCrSK after dechirp will be deduced in TDSC and a decision criterion for FCrSK is designed from spectral energy concentration to utilize multipath energy. And this decision criterion is more suitable for FCrSK in TDSC than frequency domain peak to average ratio (FPAR). Besides, the system has no rely on channel state information and has better performance at high SNR in TDSC than Lora. Furthermore, it is superior to Lora in and time-varing doppler channel. So FCrSK with this criterion can provide a good way for high reliability and low latency communication in future. © 2022 IEEE.
