Synopsis

Depicted in this research is a user-friendly MATLAB program that can be used to calculate co-channel interferences, both in the downlink and the uplink of a single satellite/space-based mobile communications system that utilizes frequency reuse in spot or cellular beams. The analysis and computer code can be applied to any type of satellite or platform elevated at any height above earth. The calculation is for a given instant of time for which the system parameters are input into the program. The results obtained are for the overall carrier to interference ratio (CIR) along with CIR for both the uplink and downlink paths. An overall carrier to noise plus interference ratio (CNIR) is also calculated, which exemplifies the degradation in the carrier to noise ratio (CNR) of the system due to interference. Comparisons for systems with different system scenarios are also made. In conclusion, the co-channel interference can cause substantial degradation to the overall CNR of a system, and should be included as an integral part of the satellite link analysis.
