In HF radio communications, the performance is often limited by the large amount of mostly narrowband interfering signals from other HF users. Therefore, when evaluating HF spreadÂspectrum systems, a statistical model of the interference is necessary. In this work, we perform a comparison between a frequencyÂhopping (FH) and a directsequence (DS) spreadspectrum system, for an interference model based on the HF congestion prediction model by Laycock and Gott. The performance measure used is the error probability for the uncoded bits. The results show that the FH system performs better than the DS system on the interferencelimited HF channel. The performance of the FH system can also be further improved by introducing soÂcalled adaptive frequencyhopping, which implies that the system will adaptively use the least interfered channels for the communication.
