Performance evaluation of diversity antennas in multipath environments of finite richness

The simulation tool introduced is extended further to include the emulation of non-uniform multipath environments. This extension creates a trend to generalize the definition of effective diversity gain to be applicable to non-uniform multipath environments too. We introduce the richness threshold as a further metric for diversity performance of multi-port antennas. By virtue of this novel parameter, we demonstrate that beam-forming, which is ineffective in a rich isotropic multipath environment, is beneficial in non-rich isotropic multipath environments.
