Satellite Communication Coding Design Based on Large Frequency Reuse Factor and Precoding Technology

It is an inevitable trend for high-throughput satellite systems to adopt full frequency multiplexing technology. Therefore, this paper optimizes the design of satellite communication(SC) coding based on large frequency multiplexing factor and precoding technology(PT). The static soft frequency reuse and dynamic soft frequency reuse of large frequency reuse factor(LFRF) are discussed. The PT is briefly analyzed; Through the experimental analysis of the optimization of SC coding design, it shows that the optimization design scheme of the LFRF and PT proposed in this paper obviously eliminates the co frequency interference between beams, and improves the system capacity and has a certain robustness.
