Simulation Results

Relaying is one of the key technological enhancements for the data rate and coverage requirements of wireless networks. The interference alignment (IA) is a promising method for co-channel interference in wireless networks. In this paper, we investigate the quantize-and-forward (QF) relaying strategy with IA in the relay networks. The multi-user transmission aided by the relay is a common case in the wireless networks and can be modeled as multi-user relaying interference channels. We design a method for QF relaying strategy at the relay and propose precoding of IA to process the interference at each user. Then we derive the sum rate of the system and simulate it with the varying transmitted power and the distance between the user and the relay. The simulation results show that, the sum rate of designed QF relaying with IA has a better performance than those of the existing methods or processed algorithms.
