摘要：Higher data rate and easier communication is required for commercial wireless communication system.System design in the multipath fading is channelled in wireless communication system because which gives weaksignal strength and enhance the bit error rate of communication system. Multi input- multi output (MIMO) system isused to overcome this drawback. Multiple antennas are used to gives higher data rate, higher transmit and receivediversity through spatial multiplexing in wireless communication system. This paper presents a detail study of bit errorrate(BER) analysis of multi input- multi output(MIMO) system under AWGN(additive white Gaussian noise) andRayleigh fading communication channel. It is used maximum like hood detector and maximal ratio combining at thereceiver side and encoded by Almouti space time block code at the transmitter sides. Almouti space time block code(STBC) gives the transmit diversity. System result is observed by BPSK modulation technique using MATLAB.Simulation result gives the comparison between two channels, AWGN channel has better achievement.
