MIMO reception in Rayleigh and Rician fading with imperfect channel estimation

Abstract

Wireless communication technology has undergone significant improvement over the past decades which has lead to the higher data rates and better bit error rate (BER) performance. There has been increase in the demand for high channel capacity in multipath fading environment which is possible by Multiple Input Multiple output (MIMO) system. MIMO system increases the capacity, makes communication more reliable and reduces the effect of channel fading. Channel State Information (CSI) at the receiver needs to be estimated to improve the performance of detection and estimation of symbols.
