Additional intra-and/or inter-system interference reducing systems and methods for satellite communications systems
First Claim
1. A method of operating a satellite radiotelephone communications system, the method comprising:
- receiving first radio signals by a first satellite, the received first radio signals including a desired signal using a frequency and an interfering signal using the frequency;
combining the first radio signals based on a first performance criterion to generate a first output signal;
receiving second radio signals by a second satellite, 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.

Abstract
First radio signals are received by a first satellite, the received first radio signals including a desired satellite uplink signal transmitted from a first source using a frequency assigned to the first source and an interfering signal transmitted from a second source using the frequency assigned to the first source. The first radio signals are combined based on a first performance criterion to generate a first output signal. Second radio signals are received by a second satellite, the received second radio signals including a measure of the desired signal. The second radio signals are combined based on a second performance criterion to produce a second output signal. The first and second output signals are combined to generate an estimate of the desired satellite uplink signal.
