Abstract
This letter considers the amplify-and-forward (AF) system consisting of a destination node with M antennas, and a source node and N relay nodes with a single antenna each. The “best” relay, which is selected depending on the instantaneous and partial channel knowledge, is assigned to assist the source transmission. By deriving the lower and upper bounds for the outage probability of the system, we show that the diversity order of min(M,N) can be achieved. This analysis gives a promising solution to improve the diversity performance of partial relay selection scheme.
