Jadhav Journal On Wireless Communication Networks 2320 - 2351 3 4 1 7 Multiple Input Multiple Output (MIMO), Maximal Ratio Combining (MRC), Multipath Fading, Ergodic Channel Capacity, Bit Error Rate (BER) Multiple Input Multiple Output (MIMO) technology has important role in wireless communication systems; because it offers significant increase in data rate and link range without additional transmit power. The conventional MIMO uses 2 to 4 antennas per terminal. In order to achieve high spectral efficiency, the concept of large –MIMO is emerging. The implementation of large-MIMO undergoes complex process at receiver end in estimation and detection. The several aspects of wireless communication based feedback with multiple antennas, such as the estimation of the Channel State Information (CSI), the quantization of the CSI with a finite number of bits to enable its feedback and effect of errors in the feedback channel on the performance of the communication system are need to be considered. In this paper, the Ergodic Channel capacity calculations for large-MIMO are presented. The Bit Error Rate (BER) analysis is carried out for different modulation techniques using OFDM for the case of Multiple Input Single Output (MISO) systems using beam forming technique and for the Single Input Multiple Output (SIMO) system using Maximal Ratio Combining (MRC) technique.
