Our research has partly been supported by the Nutek program on
Digital Communications and later on Telecommunications
since 1988. The paper summarizes our activities in 1992-1993.
In the project, work has been carried out on problems
spanning the fields of Signal processing, Communications,
A guiding principle has been to formulate general
problems, originating from relevant applications. Here
equalization of fading mobile radio channels
has served as a main source of inspiration, and also a useful
application for testing new ideas.
The aim is, however, to develop
general tools and methods useful for a large range of problems.
Very central in our work is the desire to obtain
explicit solutions and to gain engineering insight.
As a means to accomplish that,
the Polynomial Systems framework has been used.
It describes linear dynamic systems in input-output form,
and has been useful in our study of
general IIR-filter structures, implicit adaptive schemes,
probabilistic descriptions of model errors, and utilization of
a priori information. Our long term goal
is to provide a general model-based design concept,
for solving a variety of problems in Signal Processing,
Communications and Control.
The publication of the book chapters
are steps towards this goal.
A short summary of the main activities, and a list of publications,
are given in the paper.
