摘要

本文研究了一种基于l相电平相干频率/相位调制(LCFPM)的栅格编码方案，用于加性高斯白噪声信道。在功率和带宽效率方面，与传统的频率和相位联合调制进行了比较。与传统的双频频相联合调制相比，栅格编码的LCFPM在功率和带宽效率方面具有很强的竞争力。

Trellis coding of L-phase-level coherent frequency/phase modulated signals

This paper investigates the trellis-coded schemes based on a newly developed L-phase-leveled coherent frequency/phase modulation (LCFPM) for the additive white Gaussian noise channel. Comparison with conventional joint frequency and phase modulations is given in terms of power and bandwidth efficiencies. It is found that the trellis-coded LCFPM is highly competitive in power and bandwidth efficiencies in comparison to conventional dual-frequency joint frequency and phase modulations.
