Fading and interference mitigation in multi-antenna wireless transmission

In this paper, we propose a transmitter based scheme to simultaneously mitigate fading to a desired receiver and co-channel interference to an interferee. We focus on downlink transmission at the base station with multiple antennas at transmit and a single receiver at the intended and interferee rec...

Summary:In this paper, we propose a transmitter based scheme to simultaneously mitigate fading to a desired receiver and co-channel interference to an interferee. We focus on downlink transmission at the base station with multiple antennas at transmit and a single receiver at the intended and interferee receivers. We show how appropriate pre-coding and space-time coding can be combined to maximize link performance subject to a specified degree of co-channel interference suppression and assuming a limited amount of information at the transmitter. The resulting solution is compared to transmit beamforming and demonstrates performance improvements due to the additional transmit diversity extracted. In addition, we propose a suboptimal but low complexity implementation of the technique and a modification of the technique to account for errors in the parameters used by the transmitter.
