We consider the problem of sending a bivariate Gaussian source over a slow-fading multiple-access channel (MAC) with no channel state information at the transmitters. A joint source-channel coding (JSCC) scheme is constructed using hybrid digital-analog (HDA) coding techniques to minimize the average distortion over the uncertain MAC. Numerical results show that, under Rayleigh fading, the proposed HDA scheme can outperform the source-channel separation approach and the uncoded approach as the power-to-noise ratio increases. A HDA scheme based on orthogonal multiple access is designed for comparison.

A low-power wearable wireless sensor measuring both molecular biomarkers and physiological signals is proposed, where the former are measured by a microfluidic biosensing system while the latter are measured electrically. The low-power consumption of the sensor is achieved by an all-analog circuit implementing Analog joint source-channel coding (AJSCC) compression. The sensor is applicable to a wide range of biomedical applications that require real-time concurrent molecular biomarker and physiological signal monitoring.

In this paper, we design a unified framework decoder for relay systems with iterative decoding. In the proposed scheme, the source node needs to transmit a correlated content to a destination with the help of a relay. Then, a distributed joint source channel (JSC) Low-Density-Parity-Check (LDPC) encoding is applied at the source and the relay. The destination receives simultaneously the source compressed data from the source node, and the source/channel encoded data from the relay node. The cooperative network is mapped into a factor graph on which message passing iterative decoding is applied to estimate the source information. The JSC decoder takes into account the source-relay correlation which involves remarkable improvements even if errors occur at the source-relay link. The Bit Error-Rate (BER) system performance are investigated for different scenario, according to the relay position, and it is shown that the performance of the proposed cooperative scheme is typically about 0.5-1.0 dB better than an equivalent rate point-to-point system.

We consider a wireless network where each user/sensor wishes to communicate an image to a central base station for the purpose of classifying images with intrinsic class imbalance. We introduce a new framework for encoding images where a single neural network is used to perform joint source coding and channel coding for the purpose of classification. The main novelty in the proposed approach is that all users simultaneously transmit features extracted from their image over the air, and inference is performed directly on the received signal (noisy sum of the transmitted signals) using neural group testing. We show that our framework can achieve significantly lower communication and computational costs than traditional communication schemes while offering privacy and better classification performance.

This paper proposes for the first time, the very large scale integration (VLSI) architectural techniques for error resilient joint source channel coding (JSCC) of arithmetic codes (AC). When implemented on a 0.13 mu m standard cells technology running at 340 MHz, achieves a decoding throughput of up to 125 kbit/s, 58 times better than the standard implementation.

Error resilient video coding critically relies on the accuracy of end-to-end distortion estimation. An established solution, the recursive optimal per-pixel estimate (ROPE), is based on tracking the first and second moments of the decoder reconstructed pixels. This paper is focused on an alternative estimation approach, the spectral coefficient-wise optimal recursive estimate (SCORE), whose recursion is performed in the transform domain. The SCORE formulation is extended to derive a new technique for effective end-to-end distortion estimation, which accounts for sub-pixel motion compensation. Specifically, this technique exploits properties of the transform, such as coefficient de-correlation and energy compaction, to overcome ROPE's remaining shortcoming due to the proliferation of cross-correlation terms requiring excessive complexity or relatively crude approximations. Experiments show that the accuracy of SCORE matches ROPE in the full-pixel motion compensation setting, where ROPE is known to be optimal. More importantly, in the problematic setting of sub-pixel motion compensation, SCORE substantially outperforms ROPE and yields highly accurate distortion estimation.

The optimal FEC code rate decision is a crucial procedure to determine the optimal source and channel coding rates to minimize the overall picture distortion when transporting video packets over packet loss channels. To avoid the complex modeling procedure, we propose a simple but accurate joint source-channel distortion model to estimate channel loss threshold set for optimal FEC code rate decision.

Recently, task-oriented semantic communication has received increasing attention due to its potential to transform the communication landscape by going beyond the Shannon paradigm. While most existing researches focus on a single task, we propose a multi-task semantic communication system for text tasks, inspired by the impressive results of multi-task learning and bidirectional encoder representations from transformers (BERT). Based on BERT, the proposed system extracts semantic information from the text at the transmitter and then transmits it to the receiver, which aims to accomplish a series of different tasks. The transmitter and receiver would be trained jointly in an end-to-end manner. Compared with the traditional communication system, the proposed model is more robust to distortion caused by physical channels and exhibits better performance, especially in the low signal-to-noise ratio regime. Moreover, we investigate the relationship between the number of tasks and the required length of transmitted symbols in a multi-task setting.

An efficient approach for transmission of scalable video over erroneous channel is proposed. The proposed approach jointly optimises the bit allocation between a wavelet-based scalable video coding framework and a forward error correction codes. The forward error correction is based on the two-dimensional error protection scheme which applies unequal error protection in temporal-spatial layers as well as in quality layers. The scheme minimizes the reconstructed video distortion at the decoder subject to a constraint on the overall transmission bit-rate budget with limited complexity. This minimization is achieved by exploiting the combined scalability in temporal-spatial and quality domain. Experimental results clearly demonstrate the superiority of the proposed approach over conventional forward error correction techniques. It also significantly improves the performance of end to end scalable video transmission at all channel bit rates.

In this paper, we propose a decoder which reconstructs signals which are joint-source channel encoded using oversampled filter banks. The decoder is based on operating the para-pseudo-inverse corresponding to the cascaded transform function consisting of the source encoder and the erasure channel on the received signal. Hence, the proposed method minimizes the reconstruction mean square error. The decoder consists of a filter bank which can comprise of FIR or IIR filters depending on the erasure channel. Hence the computational complexity of the decoder is also lower compared to earlier proposed techniques. The theoretical results are validated by simulations using image data.
