Reordered Exponential Golomb Error Correction Code for Universal Near-Capacity Joint Source-Channel Coding

Joint Source-Channel Coding (JSCC) is a powerful technique that allows for the efficient transmission of information by simultaneously considering characteristics both source and channel. The recently proposed Exponential Golomb Error Correction (ExpGEC) Rice (REC) codes provide generalized JSCC schemes near capacity coding symbols drawn from large or infinite alphabets. Yet these require impractical decoding structures, with buffers inflexible system design, this was mitigated introduction Reordered Elias Gamma (REGEC) which itself had limited flexibility regards to distribution. In paper, we propose novel (RExpGEC) scheme, designed flexible practical near-capacity performance. RExpGEC encoder decoder are presented its performance analysed using Extrinsic Information Transfer (EXIT) charts. shown via trellis design. Finally, Symbol Rate (SER) code compared when integrated into RExpGEC-URC-QPSK scheme against other comparable Separate Source Channel (SSCC) benchmarkers. Specifically REGEC-URC-QPSK serial concatenation Convolution Code, becomes Exp-CC-URC-QPSK scheme. Our simulation results demonstrate gains benchmarkers in providing reliable communications. Specifically, outperforms SSCC uncorrelated Rayleigh fading channel 2 3.6 dB (dependent on distribution). Furthermore, consistently operates within 2.5 measuring Eb/N0, whilst SNR These come at cost complexity, whereby times more complex than under certain conditions. This paper highlights unique capabilities as high performance, technique.
