Bit error rate analysis of cognitive radio under fading channels

The Silver code has been proposed as a 2 × 2 space time block code that accomplish the optimal diversity — multiplexing gain tradeoff for a multiple antenna system in Cognitive Radio Network. In this paper the decoding methodology for the Silver code is analyzed, followed by performance analyzing with the Alamouti code and V-BLAST in Rayleigh fading environments. Simulation results show that the Silver Code outrun both the Alamouti code and V-BLAST at high SNR levels.
