Co-channel interference reducing arrangement in a satellite communications systems, and method

A method of operating a system radiotelephone communications satellite, wherein the method comprises: receiving the first radio signals on a first satellite, wherein the first received radio signals including a desired signal using a frequency, and an interference signal using said frequency; combining the first radio signals based on a first performance criterion to generate a first output signal; receiving the second radio signals at a second satellite, wherein the received second radio signals including a measure of the desired signal; combining the second radio signals based on a second performance criterion to produce a second output signal; and combining the first and second output signals to generate an estimate of the desired signal.
