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.

Most practical filters exhibit steady roll-off characteristic, in
contrast to the sharp transition from the pass and stop bands. The important families of filters
are: Butterworth, Chebyshev and Elliptic. As part of this lab, we study and design Butterworth
filters. Butterworth filters are simple to design and have a maximally flat pass band response.
In contrast the Chebyshev and Elliptic filters are difficult to design and have ripples in pass/stop
band but have sharper roll off characteristics than Butterworth filters.
