Abstract :
A real-time software simulator of wideband HF (high frequency) channel model is presented. Using the tapped delay line structure of narrowband Watterson model, the delay power profile of the wideband HF channel model is sampled into discrete points, dividing each propagation path into series of sub-paths. The deterministic phase function and stochastic modulation function is applied. The sum of all sub-paths forms the output signal. Simulation results show the validity of the proposed simulation model. The resulted wideband HF channel simulator is easy to deal with the simulation of HF channel with varying parameters and is convenient to be implemented in the hardware simulator of HF channel.
