Original Title:
RF-Υποσύστημα στα 2.4GHz για ένα 2x2 ΜΙΜΟ test-bed: Σχεδιασμός και Αξιολόγηση επιδόσεων
Translated title:
RF-Sub-System at 2.4GHz for a 2x2 MIMO test-bed: Design and Performance Evaluation
Summary:
The main goals of this thesis are the study and understanding of the operation
of a
MIMO system-test bed.
The implementation of the 2x2
MIMO system was done after the optimization of a SISO
system which had already been implemented in the WiCom Lab
of Institute of Informatics and Telecommunications (IIT),
NCSR “Demokritos".
In the first chapter of the thesis there is a report about the operation of MIMO
systems.
In the second chapter, we present the basic operating parameters of a
wireless system.
This work continues with the proposal of some solutions for the problems
referred while, after a market- research is made. The
forth chapter begins with the description of the process followed for this
optimization.
This chapter closes with a reference to a paper
Published.
In the fifth chapter is presented an analysis of the steps followed for the
implementation of the two RF chains of the MIMO system end measurements of LOS
and Ν-LOS environment, while a comparison
between the performance of SISO and MIMO systems is made also.
In the sixth chapter some methods for further enhancement of the system are
presented, while in the seventh chapter the bibliography of the thesis is
presented.
