Lab: Interference measurements in a DVB-T system


Introduction

In this laboratory work you learn the basics features of DVB-T physical layer operations.

You will learn the structure of the OFDM signal and you understand the basics principles of coding.

You will know how a DVB-T system is parameterized and how different options sustain

disturbance from other transmitters.

 

In the laboratory work you use a DVB-T system for investigating the impact of the interference

on the system performance. After the laboratory works you will know what the interference

is how to classify and characterize the interference and how different types of interferences

impact the receiver performance.

 

After this laboratory you will be able to construct a measurement system for measuring co-channel

and adjacent channel interference. You know how the deployment of strong codes impacts

the performance of receiver and how the receiver has to be protected.
