International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / The Nova HYPERMOD demodulator operates in three modes, the classic pulse-code
modulation/frequency modulation (PCM/FM), sometimes known as continuous phase frequency shift
keying (CPFSK) mode, shaped offset quadrature phase shift keying (SOQPSK) mode, and continuous
phase modulation (CPM) mode. Of interest to this paper is SOQPSK mode which is a waveform similar
to the Advanced Range Telemetry (ARTM) Tier I waveform, Feher’s Quadrature Phase Shift Keying, B
version (FQPSK-B) revision (Rev) A1. Also considered is another variant, FQPSK-JR. This paper
will outline the cross compatibility and resynchronization speed of these waveforms based upon
ARTM-adopted demodulator performance tests. The results of these laboratory tests comparing the
HYPERMOD demodulator, the enhanced Tier I demodulator, and the current Tier I reference
demodulator, both from RF Networks, will be presented.
