Unified Performance Analysis of Two-Hop Amplify-and-Forward Relay Systems with Antenna Correlation
The authors present a unified performance analysis of a system in which the source and the destination are equipped with multiple antennas and communicating via a single antenna relay. Their studies can be divided into two parts. First they consider a system with Maximal Ratio Transmission (MRT) at the source and Maximal Ratio Combining (MRC) at the destination by assuming general correlation structures with arbitrary eigenvalue multiplicities at the source and the destination. Then a system with Transmit Antenna Selection (TAS) at the source with uncorrelated antennas and MRC at the destination with correlated antennas is investigated.
