摘　　要：简述了正交频分复用技术的发展及特点,论述了其原理及实现方法,构建了OFDM系统的实现框图,并将其应用到无线信道中。理论上得到频域均衡单载波系统复杂度和性能与多载波系统相当,且可以与多载波系统共存的结论,已被IEEE 802.16建议在宽带无线接入中采用。This paper describes the development and characteristic of OFDM technique,then describes its principle and realization method. Designing the realizing architrave of OFDM system,and then it is applied into wireless channel. The complexity and performance of frequency field equilibrium signal- carrier wave system is equal to multi- carrier wave system,and can be coexistence with multi- carrier wave system in theory,and is suggested by IEEE802.16 to apply into wireless connection.
