Carrier-phase synchronization can be approached in a
general manner by estimating the multiplicative distortion (MD) to which
a baseband received signal in an RF or coherent optical transmission
system is subjected. This paper presents a unified modeling and
estimation of the MD in finite-alphabet digital communication systems. A
simple form of MD is the camer phase exp GO) which has to be estimated
and compensated for in a coherent receiver. A more general case with
fading must, however, allow for amplitude as well as phase variations of
the MD.
We assume a state-variable model for the MD and generally obtain a
nonlinear estimation problem with additional randomly-varying system
parameters such as received signal power, frequency offset, and Doppler
spread. An extended Kalman filter is then applied as a near-optimal
solution to the adaptive MD and channel parameter estimation problem.
Examples are given to show the use and some advantages of this scheme.

说明: 广义S变换
作为小波变换和短时傅里叶变换的继承和发展, S 变换采用高斯窗函数且窗宽与频率的倒数成正比,免去了窗函数的选择和改善了窗宽固定的缺陷,并且时频表示中各频率分量的相位谱与原始信号保持直接的联系,使其在 PQD 分析中可以采用更多的特征量,同时, S 变换提取的特征量对噪声不敏感,因此,近年来众多学者纷纷采用 S 变换并结合其他分析工具应用于 PQD 的分析,产生了大量研究成果。(Generalized S-transform)
