Abstract

In this paper, a multiuser multiple-input-multiple-output, cognitive radio (CR) system has been analysed with transmit antenna selection (TAS) at CR base station transmitter and generalized selection combining GSC (N r , N c ) at each CR user. Multiuser diversity gain is obtained by selecting best CR user on the basis of instantaneous post processed signal-to-noise ratio (SNR) at the CR-Rx. The improved average post processed SNR and ergodic capacity of proposed TAS/GSC system is a function of best chosen receiver branches. The proposed TAS/GSC system is constrained by interference temperature limit ‘Q’ at primary user (PU) Rx, which degrades overall throughput hence peak power (P p ) of CR base station is set to be less than ‘Q’. We also derive analytic expressions for ergodic capacity and average post processed SNR. The simulation result validates with analytical result.
