Performance of Interference Alignment in Cognitive Radio Networks under Interference Leakage

Abstract

Interference aligment in cognitive radio networks has recently been studied in the literature to improve the system performance. This paper investigates the performance of interference alignment based cognitive radio network under interference leakage. The closed-form mathematical expressions of the average data rate and the outage probabilty are derived under the interference leakage of the secondary network users on the primary network. The theoretical analyses for wireless communication channel is presented considering with different signal to noise ratio values under Rayleigh fading channel.
