Improved methodology to compare diversity performance of several multi-antennas systems

This proposed methodology is an interesting tool which allows to compare several multi-antennas systems designed for a given application. This comparison is made possible thanks to the introduction of the referenced diversity gain. This methodology has the advantage to take into account a group of pondered situations which describes a real application. It is now possible for manufacturers to choose the most adapted system by considering antennas properties (efficiency, size, cost), radio link improvement and combining method complexity. Moreover, simulated or measured values can be used for distribution of incoming radio waves and radiation patterns of antennas.
