From: Training design for precoded BICM-MIMO systems in block-fading channels
Comparison of FER performance obtained with the optimal PPSAM, sub-optimal PPSAM and PSAM scheme-over a 4 × 2 block-fading channel with n c = 2, when N = 2 and n p = 2 after 1 and 5 iterations of iterative channel-estimation/demodulation/decoding.
