摘要
本文系统地分析了编码正交频分复用系统的技术状态,并通过计算机模拟,验证了编码正交频分复用系统对于卫星数字信息传输是十分有效的,得到了在不同信道条件下的模拟结果.
In this paper the technical stale of the coded orthogonally frequency division multiplex system is analysed in a systematic way.Through the computer simulation, it is proved that the coded orthogonally frequency division multiplex system is effective for digital information satellite transmission.The simulation results are obtained under different channel conditions.
