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.

这里提供了两个消除趋势相的matlab程序
在故障诊断中 要对信号进行频谱分析 而在频谱分析前要消除趋势相 这样得到的频谱 能更好的反映故障 有利于进一步诊断(Here are two trends in the elimination phase of the matlab program in fault diagnosis to the signal spectrum analysis and spectrum analysis in the former to eliminate the tendency of such spectrum can be better reflected further in favor of fault diagnosis)
