The standard codes are simulated for two cases of decoder-to-demodulator extrinsic information feedback: BICM, in which no information is fed back from decoder to demodulator, and BICM-ID, in which information is fed back to …
Web26 jun. 2024 · Furthermore, the soft bit-flipping prior-processing and the C2V-based hard decision updating method are combined in VN to reduce the decoding latency. A (2048,1723) stochastic LDPC decoder is designed in the TSMC 65 nm process to demonstrate the proposed decoder architecture. WebHowever, LDPC codes did not provide significant improvement over a strong turbulence channel with σ I 2 = 1.4. That is because the performance of LDPC-coded schemes depends on the input of the LDPC decoder, i.e., soft-demapping information. Hence, the performance of a coded CAP scheme with spatial diversity was studied to mitigate the ...
