The Variable Speed HF Modem Modulator Design
Abstract
The battery-operated, Variable Speed High Frequency (HF) Modem transmits data at 2400 bits per second (bps) over HF radio links. Variable data rates of 2400 and 1200 bps are supported. This compact, lightweight unit is a processor-based implementation based on the TMS32OC25 digital signal processor. The modem waveform is compatible with the AN/USQ-83(V) and ANDVT TACTERM equipment. This report presents a functional overview of the hardware and software design of the Variable Speed HF Modem modulator. (Author)
