چکیده
In this research paper basic concepts of 5G MIMO system is discussed in detail and BER performance of OFDM system for 5G MIMO system is simulated and results are shown on display. A novel technique CMA method to minimize PAPR reduction is proposed so that bit error rate performance can be improve significantly. Number of symbol considered 100, number of transmitter antenna is taken two and number of receiving antenna is taken three for analyzing BER performance and channel estimation using least square estimator.
