Serially Concatenated Joint Source-Channel Coding for Binary Markov Sources [PDF]
, 2011 In this paper, we propose a joint design of serially concatenated source channel coding for binary Markov sources over AWGN channels. To exploit the memory structure inherent within the sequence output from the source, modifications are made on the BCJR ...

Two-Dimensional Iterative Source-Channel Decoding for Distributed Video Coding [PDF]
, 2014 Motivated by the Joint Source-Channel Decoding (JSCD) principle of exploiting the source redundancy, in this treatise we study the application of iterative source-channel decoding (ISCD) conceived for distributed video coding (DVC), where the video ...

Soft-In Soft-Out Polar Decoding Aided Three-Stage Concatenated Iterative MIMO-Turbo Transceivers
IEEE Open Journal of Vehicular Technology, 2023 A novel Soft-Input Soft-Output (SISO) polar decoding algorithm is proposed, which is capable of iterating between an inner and outer decoder in a three-stage serial concatenated iterative receiver. The proposed polar decoding algorithm leverages a hybrid

Efficient Quantization with Linear Index Coding for Deep‐Space Images
Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018 Due to inevitable propagation delay involved in deep‐space communication systems, very high cost is associated with the retransmission of erroneous segments. Quantization with linear index coding (QLIC) scheme is known to provide compression along with robust transmission of deep‐space images, and thus the likelihood of retransmissions is significantly

A Jointly Optimized Variable M‐QAM and Power Allocation Scheme for Image Transmission
Journal of Computer Networks and Communications, Volume 2012, Issue 1, 2012., 2012 We introduce an improved image transmission scheme over wireless channels with flat Rayleigh fading. The proposed scheme jointly optimizes bit power and modulation level to maximize the peak signal‐to‐noise ratio (PSNR) of the reconstructed image and hence improves the perceptual quality of the received image.
