Abstract

Abstract:
This paper presents a modification of the Maximum Ratio Combining (MRC) technique
used in antenna diversity systems. The modified scheme requires only one RF down
conversion chain and one matched filter for the whole system and therefore provides
significant complexity reduction. The bandpass equivalent of the conventional baseband
MRC scheme is derived first, and a modification is proposed to attain a practical
implementation. Simulation results for different modulation schemes verify the validity
of the proposed model and show no loss of performance with respect to the derived
bandpass scheme.
