| Abstract: | HF wireless communication has been widely used in the military communication. HF Channel Simulator an important testing tool of HF communication equipment, which can simulate the main characteristics of HF channel, such as multi-path, Rayleigh fading and Doppler shift. Based on HF communication theory, the paper introduces the multi-path delay effects, and presents a new signal-delay method. The method is designed based on FPGA and FIFO, and the testing results show it can meet the requirements of design. |
