Comparison of antenna diversity schemes

Abstract

This paper compares 4 kinds of simple diversity schemes for an indoor scenario at 2.4 GHz: polarisation, dual antenna, antenna and polarisation, and triple antenna for an indoor scenario, all combined according to 5 different techniques. Useful parameters are extracted statistically. We conclude that the power combining method gives the best results, and that the extra complexity of the 3 antenna case is not always justified from a cost viewpoint.
