Performance of ANDVT HF Modem with Peak Clipping.

Abstract

The performance of the signal design for the ANDVT hf modem was investigated for the Gaussian channel with variable amounts of peak clipping on the modulator output. The advantage is an increase in average power when operating in a peak power limiting situation. A recommendation is made for use of 8.0 dB of clipping on the 16 tone DPSK signal used for transmitting the message indicator and 9.5 dB of clipping on the 39 tone DPSK signal used for transmitting digital voice.
