We investigate a limited feedback precoder based on symbol pairwise error probability (PEP) for a block-faded $K \times n_{t}$ downlink multiple-input multiple-output (MIMO) channel. In the considered system, $K=\lfloor n_{t}^{\alpha }\rfloor $ single-antenna users feedback quantized channel state information to the $n_{t}$ -antenna transmitter using $B$ bits per-transmit-antenna per user....
