Coding & Compression main course

The Coding and Compression course is intended for Master 1, Telecommunications students and anyone who would like to learn about coding information.

Telecommunication is the transmission of information over a distance from a source to a destination through a channel. Coding is an essential part of the transmission chain. It represents the set of operations performed on the output of the source, which can be modulation, compression, scrambling, adding redundancy to combat the effects of noise, etc. These operations aim to make the output of the source compatible with the channel. The decoder at the end must be able to restore the information provided by the source in an acceptable way.

Coding is adopted to solve two major problems in transmission:

  • Efficiency: This is the role of the source encoder. It seeks to eliminate all possible redundancy in the message from the source to have a maximum compression rate.
  • Reliability: This is the role of the channel encoder. It serves to protect the data against errors that can occur on the channel during transmission and then to reconstitute the message exactly or sufficiently close to the emitted message.
