On diversity combining techniques in non-cooperative communications

Diversity combining technique is an effective method to combat the multipath fading in wireless channels. However, the traditional diversity combining methods, such as maximal-ratio combining (MRC) and equal-gain combining (EGC) are not suitable for non-cooperative communications. In this paper, selection combining (SC) is introduced into the non-cooperative communication systems, which is very easy to implement. Simulation results validate the effectiveness of this SC method.
