Space-based communication system and method with continuous channel reuse maintenance
First Claim
1. A method of reuse channel management, the method comprising the steps of:
- (a) computing interference potentials between a reference reuse unit being used by a first satellite and reuse units being used by second satellites by determining each of the interference potentials based on a physical distance between a center of a first beam that uses the reference reuse unit and each of a center of second beams that use the reuse units and a correlation factor; and
(b) assigning a non-interfering reuse unit to the first satellite when each of the interference potentials are less than a threshold interference potential.

Abstract
The system (10) and method (100) adjust reuse units when nodes (e.g., satellites (20, 22)) move in a communication system (10), such as satellites (20,22) moving in their orbits around the earth in a space-based communication system (10). The method (100) and system (10) computes interference potentials between a reference reuse unit in a first reuse unit table of a first satellite (20) and reuse units being used in second reuse unit tables in second satellites (20) that are adjacent to the first satellite (20); and when the interference potentials is less than a predetermined threshold, then assigns the satellite a non-interfering reuse unit for the specific time interval.
