Multi-user Orthogonal Frequency Division Multiplexing (OFDM) have been widely adopted to combat the detrimental effects of wireless channels and enhance system throughput. Recently, interference alignment is proposed to exploit interference to enable concurrent transmissions of multiple signals. In this paper, we investigate how to incorporate interference alignment in multi-user OFDM systems. We first reveal the unique characteristics and challenges brought about by using interference… CONTINUE READING
