Coding theory

Coding theory is the study of the properties of codes and their fitness for a specific application.

Description

Codes are used for data compression, cryptography, error-correction, and more recently also for network coding.

Codes are studied by various scientific disciplines—such as information theory, electrical engineering, mathematics, linguistics, and computer science—for the purpose of designing efficient and reliable data transmission methods.

This typically involves the removal of redundancy and the correction (or detection) of errors in the transmitted data. There are four types of coding:

• Data compression (or, source coding)
• Error correction (or channel coding)
• Cryptographic coding
• Line coding
