| Abstract: | OFDM （orthogonal frequency division multiplexing） technology is a digital multi-carrier modulation technology, and the wireless multi path fading channel has good transmission characteristics. This paper describes the design short-wave radio system, which uses the OFDM technology to overcome the interference by multipath fading. The modeling by Simulink and the simulation under the Rayleigh fading channels and Gaussian channel indicate that the performance is fairly improved. |
