Frequency Selective Distortion in Case of Mimo Transmission

Dr. Vijay Tiwari 

Abstract
Use of OFDM over multiple carriers is in use for some time now. Multiple carriers’ performance relies on the diversity. In case of diversity with multiple receive and transmit antennas, every antenna receives a linear combination of individual transmissions and added noise. However concept of channel decoupling by using Single Value Decomposition (SVD) has been employed to ensure decoupling among MIMO channels. In this paper we have shown that a decoupled channel behaves as if undergoing spatial multiplexing. Transmission without distortion is always a priority and hence concept of coherence bandwidth has been considered and its effects on the channel bandwidth are reported. Doppler Shift effects over MIMO channel are discussed. Dependence of BER on SNR has been simulated for various cases where in combinations of multiple transmission and reception antennas have been discussed.
