Abstract
Full-duplex (FD) wireless communication have attracted increasing attention recently due to the potential of doubling the spectrum efficiency. However, one of the most critical challenges of FD communication is to cancel the self-interference (SI) between transmitting and receiving antennas from one device. In this paper, we focus on the pre-coding design for sum rate maximization while considering the effects of residual SI for point – to-point multiple input/multiple output (MIMO) Full-Duplex systems. The zero-forcing (ZF) method is selected to cancel the SI. The results show that, the self-interference cancellation is done by matrix pre-coding at the transmitter if the total number of transmitting antennas of two nodes is greater than the number of receiving antennas of one node. The Bit Error Rate (BER) is also evaluated in the simulation. In addition, this paper presents optimal problem when the transmission power of all antennas is smaller than the maximum transmission power of a node.
