Abstract

A wideband high frequency (HF) channel simulator is implemented in a software simulation of a direct-sequence spread-spectrum (DSSS) HF communication system. A RAKE receiver is used to mitigate the effects of multipath delay. The validity of the HF channel simulator has been demonstrated by the analysis of in-out signals of the channel simulator. It shows that the simulator accurately models a HF channel. New performance results of the system with convolutional codes and bit interleaving are advanced to demonstrate the potential of the system with proposed scheme.
