包含非线性卫星转发器的FDM系统的仿真
仿真一个从卫星到区域数据中心的下行链路（由一组6个载波构成），评估热噪声，交调（IM）失真、由滤波器造成的码间干扰（ISI）以及邻频干扰对下行链路性能的影响。
(Contains the non-linear satellite transponder FDM system simulation simulation of a regional data centers from the satellite to the downlink (from a group of six carrier composition) to assess the thermal noise, intermodulation (IM) distortion, caused by the filter inter-symbol interference (ISI) and adjacent channel interference on the downlink performance.)
