Abstract

Diversity combining is the effective to way to mitigate the effects of multipath fading. The independent signal paths have low probability of experiencing deep fades simultaneously is the fact exploited by diversity combining. In diversity combining the replicas of same information signal is combined together to obtain high SNR. The Hybrid Diversity combining techniques has been carried out to reduce the effects of fading owing to its good performance and low implementation complexity. Different Hybrid Diversity combining techniques are summarized in this paper.
