In telecommunication a diversity scheme refers to a method for improving the reliability of a message signal by using two or more communication channels with different characteristics. Diversity plays an important role in combating fading or co-channel interference and avoiding error bursts. This diversity scheme can be used in MIMO (Multiple input multiple output). By diversity schemes that uses two or more antennas to improve the quality and reliability of a wireless link. In this paper we are using different diversity i.e. MRC, EGC & SC schemes to analysis the BER performance of Multi antenna system (MIMO) system with the help of the MATLAB SOFTWARE.

Abstract


In telecommunication a diversity scheme refers to a method for improving the reliability of a message signal by using two or more communication channels with different characteristics. Diversity plays an important role in combating fading or co-channel interference and avoiding error bursts. This diversity scheme can be used in MIMO (Multiple input multiple output). By diversity schemes that uses two or more antennas to improve the quality and reliability of a wireless link. In this paper we are using different diversity i.e. MRC, EGC & SC schemes to analysis the BER performance of Multi antenna system (MIMO) system with the help of the MATLAB SOFTWARE.
