| Abstract: | A software High Frequency(HF) channel simulator based on Watterson model is presented according to the characters of multipath, fading, Doppler frequency shift and spread in HF channel. The simulator is simple, movable and low-cost; furthermore, the simulator can also be implanted into modem easily. By the modification to the key technologies of simulation, the performance of simulator is improved. Simulation results proved that the simulator is effective and available. |
