New selection diversity reception scheme effective for both frequency-flat and selective fading channels

摘要

A new selection diversity reception scheme is proposed, which combines and takes advantage of the maximum signal envelope branch selections (MEBS) and the minimum delay-spread branch selection (MDBS) schemes. The performance of the proposed scheme is theoretically investigated under frequency-flat and frequency-selective fading channel conditions and the improvement over the MEBS and the MDBS schemes is confirmed.
