Abstract

An L-phase-levelled coherent frequency/phase modulation (LCFPM) scheme is investigated. It is analysed for both spectral characteristics and bit error characteristics on the additive white Gaussian noise channel. Comparison with conventional joint frequency and phase modulations is conducted in terms of power and bandwidth efficiencies. Both uncoded and trellis coded modulation formats are considered. It is found that LCFPM is highly competitive in power and bandwidth efficiencies with conventional dual-frequency joint frequency and phase modulations after experimenting with different uncoded and trellis-coded pulsed formats
