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 (fro

采用m序列替代随机序列作为扩频码，仿真其性能；完成了与随机序列扩频性能之间的比较；完成无线多径ISI信道建模，在ISI信道下，研究了m序列与golden序列抗ISI的仿真误码率比较-M sequence used as a substitute random sequence spreading code, simulation of its performance, the completion of the comparison between the performance of rand

In a single carrier communication system, the symbol period must be much greater than the delay time in order to avoid inter-symbol interference (ISI) [1].
