Self-interference pricing for Full-Duplex MIMO systems

Full-Duplex (FD) wireless communication systems have recently been proposed as a potential technique for increasing the spectral efficiency of wireless systems. FD communication systems suffer from the self-interference generated from one´s own transmitter to one´s own receiver in the same time and frequency slot. The self-interference signal is typically significantly larger than the received signal. The majority of existing work focuses on the suppression of self-interference without focusing on the effect on the forward channel. This paper presents a self-interference pricing based approach to suppress the self-interference without overly penalizing the forward channel. Simulation results show that even in the case of high self-interference, the proposed approach can provide significant data-rate improvements.
