In the second chapter, the characteristics of short-wave channel and the typical short-wave channel models have been introduced, and ITS channel model was selected as the Implementation model of the simulator.In the third chapter, based on the goals of lace wedding dresses broadband, real-time and reconfigurable, a wide band channel simulator has been realized. First, the signal processing board was realized. It was based on industrial computer platform, and contains cheap wedding gown dresses interface, XC4VSX35 FPGA and RF interface, and can be used in real-time channel simulate. Secondly, the implementation and verification of channel simulate program of cheap evening dresses were made, and the program can process real-time signal of bandwidth of 30MHz, and the resolution of Doppler spectrum is 0.01455Hz. Finally, the control software and PCI driver were introduced. The custom made prom dresses driver is based on the Windows Driver Model, and was developed by using Driver Works.In the fourth chapter, the channel simulator has been tested. Those experiments show that the simulator can simulates multipath-delay, Doppler frequency spread and shift, large-scale fading, sell discount wedding dresses channel, single frequency interference etc. Recommended parameter ranges and tested parameter values in several typical blog lace wedding dresses communication environments were provided, and the WBHF channel simulator was used to simulate those HF communication wedding gowns dresses environments’small scale fading.The channel simulator, which was realized in this paper, can be used in Communications equipment testing, station construction, network planning and so on.
