Abstract

MIMO systems provides number of features like spatial diversity, multiplexing gain, and high spectral efficiency gain by keeping the bandwidth expansion or transmission power similar to other systems. The major concern in the system is inter symbol interference (ISI) caused by the channel. An equalizer is deployed on the receiver side to detract the effect of ISI. In this paper, simulation is done under the Rayleigh fading environment for linear equalization techniques for MIMO systems. Result shows that ISI occurred by the channel can effectively diminished with the help of Inter Equalization techniques. In the present article, a combined method is developed for canceling the interference with lower bit error rate and diminishing the effect of noise enhancement. The results show that, performance of this technique is comparatively better than conventional techniques.
