New Carrier Frequency Assignments for Minimizing Intermodulation Products in Two-Level SCPC Systems
Summary :
In this paper, we propose an efficient method (called DIRIC algorithm) to allocate carrier frequencies so as to minimize intermodulation products in two-level SCPC systems in which Hub station and many Remote stations communicate each other through satellite transponder. We also present a very efficient method to evaluate intermodulation products with substantially reduced CPU time in two-level SCPC systems. We compare and analyze the performance of several frequency allocation methods to extend DELINS-INSDEL algorithm (which is proposed by Okinaka) to two-level SCPC systems. When the proposed algorithm is applied to systems with modulated carrier, it is verified that this algorithm has the same efficiency as the unmodulated carrier. It is also shown heuristically that certain initial assignment algorithms perform better than random assignment.
