Abstract :
Multi-h continuous phase modulation (CPM) offers significant improvements over both legacy telemetry waveforms (PCM/FM) and the newly-introduced waveform (Feher (International Telemetering Conference, Las Vegas,p.27-30, 1997) patented FQPSK) in terms of spectral containment and detection efficiency, while retaining a constant envelope characteristic. This paper describes the theoretical and measured performance of the multi-h CPM waveform as well as the implementation of a suitable trellis demodulator
