Abstract [en]

High Frequency (HF) communications are of vital importance for modern military operations. Mainly because of it long communication range at a fraction of the cost of heavily burdened satellite communications frequencies. However, the noise and interference levels are high at this frequency band. Hence, intersystem interference analysis of communication platforms is an important action in order to ensure the communication capability

In this paper we show that local interference can have significant impact on the HF communication performance. The effects from interference on the HF communication system is analyzed and shown in different military scenarios as an increased bit error probability leading to a decreased operating range of the communication system or lower data rate for the service. The considered interference source is medical equipment which emission spectrum is measured and show high levels of interference in the HF band. The overall conclusion is that local interference has to be considered for HF-frequency selection. This speaks for extending present methods for frequency selection with funtionality to avoid that local interference disrupt vital HF-communication services.
