Patent ID: 6853694

Claim:
A combiner for use in a spatial diversity radio receiver which receives multiple data signals through spaced apart antennae, said combiner comprising, for two received data signals: (a) means for receiving two strength-indicative signals, each said strength-indicative signal being indicative of a strength of one of said two received data signals, and two demodulated data signals for each said two received data signals; (b) means for generating control signals responsive to said strength-indicative signals; and, (c) means for combining said demodulated data signals in specific proportions determined by said control signals where said demodulated data signals are above a predetermined combiner threshold, to provide a combined output data signal, said specific proportions being: (i) where a difference between strengths of said demodulated data signals is more than a predetermined margin: 100% of only a strongest of said demodulated data signals; and, (ii) where said difference between strengths of said demodulated data signals is less than said predetermined margin: for said demodulated data signal which is a strongest of said demodulated data signals, 50% plus a second percentage corresponding to a ratio between one-half of said difference between strengths and said predetermined margin; and, for said other demodulated data signal, 50% less said second percentage.
