Abstract
An apparatus determines an optimal antenna and frequency combination by selecting the optimal antenna from among a plurality, N, of antennas associated with a receiver and also selects the optimal frequency from among a plurality, M, of alternative receiving frequencies transmitted from a transmitter. This is achieved by determining all N×M possible antenna/frequency combinations, by determining the received signal quality at each combination, by comparing the N×M received signal qualities, and by selecting the one antenna/frequency combination having the optimal received signal quality.
