We derive the exact log-likelihood ratio (LLR) for iterative decoding of low-density parity-check codes for pilot-symbol-assisted BPSK transmission over flat Rayleigh fading channels. The bit-error rate (BER) performances of this metric are studied for various interleavers and different pilot spaci...
EXIT charts were introduced as a method for representing how the mutual information between the decoder output and the transmitted bits changes over turbo decoding iterations. It is possible to apply the EXIT chart method to LDPC codes by treating the LDPC decoder as a concatenation of variable ...
Iterative decoding of low-density parity-check codes transmitted over noncoherent channels using pilot-symbol-assisted binary phase-shift keying (BPSK) is studied. The log-likelihood ratio of the two values of each transmitted code bit is derived using the joint probability density function of the ...
摘要: decoders, the proposed decoder can efficiently reduce the decoding complexity to O(qlogq) with only negligible degradation in BER. Comparisons on both simulated BER performance and computational complexity between the proposed and existing log-domain decoders are also provided....
Decoding LDPC (Low Density Parity Check) code and graphs using multiplication (or addition in log-domain) on both sides of bipartite graph. A novel approach of decoding LDPC coded signals is presented whereby edge messages may be updated using only multiplication (or log domain addition). By ...
Iterative decoding of low-density parity-check codes transmitted over noncoherent channels using binary differential phase-shift keying modulation is examined. Using the joint estimation approach and the averaged likelihood function approach, the log-likelihood ratios of the two values of each bit, based...
