If the radio conditions are bad, source coding is reduced and channel coding is increased.

Such a tradeoff in word length is analogous to data compression and is the essential aspect of source coding.

Data compression (source coding): There are two formulations for the compression problem:

The rate of a source of information is related to its redundancy and how well it can be compressed, the subject of source coding.

Distributed source coding (DSC) is an important problem in information theory and communication.

Distributed source coding, a technique regarding the compression of multiple correlated information sources that do not communicate with each other.

Again, though the term was originally used to describe a relationship with open source coding, this component of the definition no longer is mandatory.

This source coding and decoding is carried out by codec equipment.

The platform will utilize some measure of open source coding.

The aim of source coding is to take the source data and make it smaller.
