| Abstract: | 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 signalcarrier 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. |

| Keywords: | OFDM multi-carrier wave modulate signalcarrier wave modulate frequency field equilibrium |
