Two-Branch Selection in Wireless Space-Diversity Reception: An Upper Bound for its Output Power
This paper analytically derives an upper bound for the output power of two-sensor branch-selection (a.k.a. "antenna selection," "selection diversity," or "selection combining") reception, based on an empirically proven "geometric model" of the wireless propagation channel. The derived upper bound is explicit in terms of the geometric model parameters. The tightness of this upper bound is verified by Monte Carlo simulations.
