We investigate the performance of several interference alignment (IA) schemes for a three-user MIMO channel with limited feedback. In our study, we consider traditional IA with quantized channel state information at each transmitter, and opportunistic IA (OIA) that exploits the idea of opportunistic selection to select users whose interfering channels are most aligned. The performance of the former is determined by the quantization resolution, whereas the performance of the later depends on the… CONTINUE READING
