Channel Estimation of Various Communication System with Different Modulation Technique

In this paper, we have measured channel capacity for various communication system such as SISO, SIMO, MIMO with different modulation technique like BPSK, QPSK, 16-QAM and 64-QAM. In the proposed algorithm the Bit Error Rate (BER) is less compared to conventional algorithm. The proposed algorithm is suitable for fast speed traffic that is when the speed of the mobile is very high. We have measured the channel variation and based on that bit error rate is calculated. Here, in this paper we have applied the Maximum Ratio Combining technique.
