Abstract

In this paper, a basic cooperative system with a single semi-blind amplify-and-forward (AF) relay is considered. We present a novel protocol which can adaptively determine the transmission mode according to channel conditions. The spectral efficiency of the protocol is analyzed and its average symbol error probability (ASEP) is derived. Both analytical analysis and simulation results demonstrate the validity of our design. Compared to the conventional AF protocol, a significant increase of spectral efficiency is achieved, and the ASEP performance can also be obviously improved.
