摘　　要：现代OFDM系统采用数字信号处理技术,各子载波的产生和接收都由数字信号处理算法完成,极大地简化了系统的结构,同时提高频谱利用率。详细论述了航天远洋测控系统岸船通信网络在保持卫星转发器带宽不变的前提下,利用OFDM技术提高信息传输容量的方法,深入阐述了基于OFDM技术卫星通信网络的基本原理和系统组成,对工程中需解决的主要问题提出了解决思路,并对OFDM技术在航天测量船岸船卫星通信的应用进行探讨和研究。The system of modem OFI）M adopts a digital signal processing technology and the transmission and reception of various subcarriers are completed by digital signal processing algorithm. This simplifies the system structure, improves the availability ratio of spectrum.This paper discusses in detail a method of improving the communication transmission capability based on OFDM, expatiates deeply the basic principles and system composition of satellite communication network based on OFDM, and proposes a means to solve the main problem in the engineering.
