摘要
针对短波信道多径、衰落、多普勒频移及扩展等特点,设计了一种基于Watterson模型的短波信道模拟器,该模拟器采用全软件实现,具有简单易行、可移植性强、费用低等优点,并可实时嵌入到调制解调器中。通过对仿真中关键技术进行改进,提高了系统性能。仿真结果验证了该模拟器的有效性。
A software High Frequency （HF） channel simulator based on Watterson model is presented according to the characters of muhipath, 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.
