摘要
Abstract
High-frequency（HF） communication plays an important role in military communications, because of simple equipment, low- cost good flexibility and non-destroyed performance. Nowadays, high speed, intelligentize and cyberization are the development direction of HF communication. Orthogonal frequency division multiplexing（OFDM） technique adapts for the development of HF communication. Be cause it has the character of high bandwidth efficiency, high ability of against multipath and high bandwidth spread ability. But OFDM sys tern has the sensitivity to frequency offset, and the difference of frequency between transmitter and receiver and the Doppler shifts of channel are ubiquitous in the HF communication. The multipath, frequency offset, and nonlinear disturbance in the HF channel will deteriorate the OFDM communication performance. The effect of HF channel for OFDM signals is analyzed by theory demonstrating. The analysis result is validated based on the Computer simulations and HF OFDM communication experiment.关键词
