Abstract

This paper presents the performance comparison of cognitive radio TDCS and OFDM based for MIMO system using VBLAST receiver architecture to reconstruct the transmitted data. The interference avoidance performance in terms of BER and bitrate are improved by adding multiple antennas to the use of V-BLAST technique at the receiver. The results show the most promising intereference avoidance technique combined with MIMO V-BLAST architecture to be applied in the CR system.
