Comparative Analysis of Design & Development of Various Equalization & Diversity Techniques for MIMO System
The effect of fading and interference effects can be combated with equalizer for a MIMO system. MIMO systems exploit the multipath propagation in rich scattering environment using multiple transmit and receive antennas to increase the capacity of a link. The matrix channel plays a pivotal role in the throughput of a MIMO link since the modulation, data rate, power allocation and antenna weights are dependent on the channel gain. In this case independent, identically distributed (i.i.d.) Rayleigh fading MIMO channel with m-transmit and n-receive antennas has been taken, the diversity order is almost same i.e., m x n for ZF, MRC and MMSE-filtering-based decoding.
