Abstract

Typically maritime and military users in the High Frequency (HF) band have been allocated channels with a bandwidth of 3 kHz. This narrow bandwidth has had the undesired effect of limiting the maximum data rates achievable over HF. The need for higher data rates has motivated research into waveform design using wider bandwidth waveforms. Two approaches have emerged: wider contiguous bandwidth waveforms and multiple non-contiguous 3 kHz waveforms. This paper will explore the crest factor and power amplifier implications of both approaches.
