Performance of the ZF, AMP, simplified DU-PDA, DU-PDA, PDA and MLD detectors for the coded \(N_\text {t} \times N_\text {r}\) MIMO system. Here, the performance metric is the BER, which is given as a function of a range of SNR values. The scenario presented is of the a \(4 \times 8\) MIMO with a code rate of \(R = 1/2\) and QPSK modulation, followed by the b \(4 \times 16\) MIMO also with \(R = 1/2\) and considering now the 16-QAM modulation. Note that we have omitted the SD curves here because it achieves the MLD performance
