Abstract

This letter presents a joint protograph extrinsic information transfer (PEXIT) analysis for joint source and channel coding (JSCC) with double protograph-based low-density parity-check (DP_LDPC) codes over single-input multiple-output (SIMO) Rayleigh fading channels. The impacts of source statistics and receive antenna diversity on convergence performance for the JSCC are investigated, and we find that source sparsity plays a more vital role than diversity orders in improving both convergence and error performances under fading environments.
