A novel equalization and precoding joint optimization algorithm is proposed in dual hop multiple input multiple output (MIMO) relay communication systems. This solution combines the equalization for the first stage and precoding for the second stage in relay system, therefore the joint optimization can be equaled with the unique optimization for the product matrix of detection and precoding, which avoid the non convergence problems in iterating process, compared with iterative optimization, the complexity burden of this algorithm is greatly reduced. And from simulation results the performance is only a little degraded. Therefore, when complexity and performance are considered, this algorithm reached a better compromise.

In this paper, we study the Average Bit Error Probability (ABEP) of Receive-Spatial Modulation (R-SM) in Rayleigh channels. R-SM is a multi-antenna wireless scheme that extends the concept of Spatial Modulation (SM) at the receiver side by using linear precoding. An accurate statistical framework is used for the characterization of the received signal. Using this framework, we provide novel and analytical bounds that characterize the ABEP of R-SM. Monte Carlo simulation results are used for the verification of the derived bounds. We compare R-SM against the corresponding standard Multiple-Input Multiple-Output (MIMO) scheme and show its performance. We conclude that R-SM is able to offer the same or better BER performance as traditional MIMO only when the spectral efficiency is low and the number of transmit and receive antennas is low.

In this paper, we present a high-performance hybrid linear precoding scheme for the downlink of multiuser multiple-input multiple-output (MU-MIMO) systems based on the combination of an iterative modified regularized block diagonalization (IMRBD) precoding and minimum mean square error (MMSE) precoding. The proposed hybrid diversity maximization (HDM) scheme aims to maximize the diversity gain by means of this dual-stage precoding strategy while maintaining relatively low complexity. The simulation results show that HDM precoding can provide comparable or even better performance than other iterative precoding schemes, including some of the more complex ones.

linear precoders have been shown to perform reasonably well at low SNR when the basestation of a MIMO downlink employs one-bit digital-to-analog converters to quantize the precoder outputs. However, at medium-to-high SNRs, an error floor is encountered due to the coarse quantization. This paper examines methods for slightly perturbing the transmitted signal prior to quantization in an effort to improve downlink performance at higher SNRs. The perturbation is performed with the goal of minimizing the worst-case probability of error among the user terminals, and assumes that the symbols to be transmitted are drawn from a finite alphabet constellation. Two different types of perturbations are studied, and it is found via simulation that the methods can provide dramatic gains in downlink performance.

In this paper, we study the performance of regularized channel inversion precoding in MISO broadcast channels with confidential messages under imperfect channel state information at the transmitter (CSIT). We obtain an approximation for the achievable secrecy sum-rate which is almost surely exact as the number of transmit antennas and the number of users grow to infinity in a fixed ratio. Simulations prove this anaylsis accurate even for finite-size systems. For FDD systems, we determine how the CSIT error must scale with the SNR, and we derive the number of feedback bits required to ensure a constant high-SNR rate gap to the case with perfect CSIT. For TDD systems, we study the optimum amount of channel training that maximizes the high-SNR secrecy sum-rate.

Secure transmission is becoming an essentially important aspect in visible light communication (VLC). In this paper, we investigate the designs of artificial noise (AN)-aided precoding to improve physical layer security in a multi-user single eavesdropper wiretap VLC channels. The AN-aided precoding is designed to solve the max-min fairness signal-to-interference-plus-noise ratio (SINR) problem among users in two different scenarios: unknown and known eavesdropper's channel state information (CSI) at the transmitter. In the former case, we adopt the traditional null-space AN scheme and then study the impact of the AN power on the fairness performance. In the case of known eavesdropper's CSI, the AN-aided precoding is designed in such a way that keeps the SINR of the eavesdropper below a predefined threshold. Numerical results show that in both cases, the design could significantly degrade the quality of the eavesdropper's channel, thus enhancing communication secrecy.

Differential codebook precoding is known as a capacity-achieving precoding scheme when the channel variation is slow. However, at medium to high channel variation speeds the differential codebook optimized for low channel variation speeds performs poorly compared to other precoding schemes, thereby limiting its application to practical systems. In this paper, we apply an alternating codebook technique to differential precoding to improve its robustness to high channel variability. The basic idea is creating multiple (instead of single) differential codebooks optimized for various channel variation speeds, and alternating these codebooks over time providing a virtually larger differential codebook, containing various precoding matrices optimized for different speeds, without the need for additional feedback overhead. Simulation results show that the proposed alternating differential codebook scheme not only retains the superior performance of differential precoding at low channel variation rate but, at the same time, reduces the sensitivity to high speed channel variations, resulting in a more practical precoding scheme.

This paper proposes an adaptive precoding technology for Multiple user Multiple-Input Multiple-Output (MU-MIMO) systems based on these typical precoding models's characteristics. The main idea of the adaptive scheme is switching precoding mode among these typical precoding schemes. Through observing, I find that the BER performance by using linear precoding is better than that by taking nonlinear precoding when SNR is low. The BER performance by using linear precoding is worse than that by taking nonlinear precoding when SNR is high. Then, an adaptive precoding scheme combines linear and nonlinear precoding technologies when the critical point of SNR is found. In addition, based on different configuration of User Equipment, it uses more specific precoding mode so that it makes further improvement on performance and reduces cost. In this way, this adaptive precoding scheme is considered performance in MIMO systems and complexity degree synthetically. Therefore, adaptive precoding scheme is more efficient and dynamic than traditional precoding scheme.

An Improved AOR-Based precoding for Massive MIMO Systems 18

An Improved AOR-Based Precoding for Massive MIMO Systems

Compared with traditional multiple-input-multiple-output (MIMO) systems, the number of base station (BS) antennas increased in massive MIMO systems. However, due to the huge number of antennas, linear precoding schemes are able to achieve the near-optimal performance. Conventional linear precoding schemes such as regularized zero forcing (RZF) precoding need to calculate the matrix inversion of large size which leads to high computational complexity. Although utilizing iterative algorithm approximate instead of matrix inversion can reduce the complexity, it leads to slow convergence or general bit error rate (BER) performance. To solve this problem, we proposes a linear precoding scheme based on the accelerated over relaxation (AOR) method. Moreover, we propose a simple way to choose the optimal accelerate factor so that it is only related to the system parameters and more suitable for practical application. Simulation results prove that the improved AOR-based precoding could convergence faster and had better performance of bit error rate (BER).

In this paper, a combination of Space-Time Block Coded Spatial Modulation with Hybrid Analog-Digital Beamforming (STBC-SM-HBF) for 60 GHz Millimeter-wave (mmWave) communications is proposed in order to take advantage of the merits of Spatial Modulation (SM), Space-Time Block Codes (STBC), Analog Beamforming (ABF), and digital precoding techniques while avoiding their drawbacks. This proposed system benefits from the multiplexing gain of SM, from the transmit diversity gain of STBC and from the Signal-to-Noise Ratio (SNR) gain of the beamformer. The simulation results demonstrate that the Zero Forcing (ZF) and the Minimum Mean Square Error (MMSE) precoded STBC-SM systems have better Bit Error Rate (BER) performance than the precoded SM system, and the former showed a performance degradation compared to STBC-SM system tough. Furthermore, the error performance is significantly improved by employing an array of ABF which improves the system performance as the number of antenna array elements increases due to providing a beamforming gain, which is hence of great significance to the Fifth Generation (5G) mmWave communications. In addition, it is demonstrated that a minimum of 2 antenna elements in the proposed scheme of STBC-SM-HBF are required to obtain better error performance than that of the conventional SM and STBC-SM systems under the same spectral efficiency of 2 bits/s/Hz.
