PERFORMANCE EVALUATION OF STBC CODES WITH CHANNEL ESTIMATION BY OPTIMIZED PILOT BITS

摘要: Wireless communication has made a tremendous impact on the lifestyle of human being. It is very difficult to survive without wire less in some form or other. Multi input multi output (MIMO) system plays vital rol e 4G wireless systems provide advanced data rate. In this paper, we propo se channel estimation at receiver with help pilot bits, which are known rec eiver advance and change bits BER, reduced so mu ch if increase bits. The performance evaluations validated through computer simulations using MATLAB terms BER. Simulation results show that B ER clearly outperforms conventional fix ed method.
