Abstract

Two-way radio systems covering large geographic areas must often utilize multiple receiver sites in order to provide adequate receive signal quality for in-bound transmissions, This is particularly true of systems employ- ing portable or other low-powered transmitters. In voice radio systems, a comparator is used to compare the various received signals and to select or vote the best signal for use. This is currently done by measuring the amount of high frequency noise in the received signal and selecting that signal with the least amount of noise.
