Due to time varying nature of wireless channel and due to limited sources of signal transmission and various effects such as path loss. Doppler spread, shadowing and interference make it difficult to achieve satisfactory data rates. Diversity is a technique which is used for combating fading and co channel interference and error bursts. In this paper various concepts of antenna diversity and combining techniques such as SC, MRC are discussed to combat multipath fading. BER and SNR performance of the various combining techniques are analyzed using Matlab simulation.
