| Abstract: | Orthogonal frequency-division multiplexing(OFDM)refers to a special frequency-division transmitting plan, which is not only a modulation technology but also a multiplexing one.It has many merits and is a main-stream modulation and multiplexing technology in next-generation mobile telecommunication system.The article introduces its basic principles and elaborates that the application of OFDM featured by rotating modulation can improve the telecommunication performance. In addition,the article also compares i... |
