Frequency Selective Distortion in Case of Mimo Transmission
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.
