Performance Analysis of MIMO Systems Over AWGN and Rician Channels Using QOSTBC4 as Space Time Block Coding Technique with Zero Forcing Receiver

MIMO is the technology in which multiple antennas (MIMO) are utilized as a part of wireless communication to accomplish high data rates and increasing the demand of clients in various fields. The main motive is to use spatial diversity in proper way by placing n number of antennas at the transmitting and receiving ends. This technology has different types of space time coding. In this paper analysis has done for QOSTBC4 through the comparison of AWGN and Rician channels. The number of reception antennas increases and no. of transmitting antennas is 4. This paper shows the analysis of QOSTBC4 through the comparison of different channels, such as AWGN and Rayleigh channel between the BER vs SNR for the improvement of spatial diversity.
