Cognitive Radio with Single Carrier TDCS and Multicarrier OFDM Approach with V-BLAST Receiver in Rayleigh Fading Channel

This paper presents the performance comparison of efficiency. OFDM is well known as a spectrally efficient Cognitive Radio TDCS and OFDM based for MIMO system modulation mode which due to its overlapped carrriers using VBLAST receiver architecture to reconstruct the spectrum but still orthogonal to each other, gives a higher bit transmitted data. The interference avoidance performance in rate compared to the single carrier transmission. As MIMO terms of BER and bitrate are improved by adding multiple approach can fulfil the bit rate requirement for single carrier antennas to the system and the use of V-BLAST technique at the modulation, the BER performances of single carrier and receiver. The results show the most promising interference multicarrier modulation need to be compared. avoidance technique combined with MIMO V-BLAST architecture to be applied in the CR system. This paper is organized as follows. Section II describes the TDCS architecture in transmitter and receiver including...
