Log-likelihood metric for LDPC coded BDPSK-OFDM transmission
Shengjiao Cao, Pooi‐Yuen Kam, Changyuan Yu · 2012
We investigate the performance of LDPC codes with BDPSK-OFDM modulation over the AWGN channel with unknown carrier phase. The proposed A-TSOI-LLR metric is performing better and more tolerant to SNR estimation error than the Gaussian metric.
