Communication using the High Frequency (HF) band has been a primary means of beyond line of sight communication. Despite the advent of several other kinds of transmitting media it continues to be used extensively owing to the fact that it is economical and flexible. The use of a channel simulator for evaluating the performance of a data transmission system offers several advantages. The HF channel model is simulated and degree of accuracy between input and output is observed. Efficiency of this model derived from the decision feedback equalizer is good even under severe distortion.
