The processing of information via the use of applied mathematics and electrical engineering
- Audio coding - the translation of auditory information into digital code
- Channel coding - code used to protect information over a channel by correcting errors resulting from noise or other interference
- Codes - rules for converting one piece of information into another
- Communication channels - a physical or logical connection between two points that allows for the exchange of an information signal
- Decoding - translating from an coded message into the original language or form
- Encoding - the process by which information from a source is changed into symbols to be communicated
- Error compensation - the encoding or transmission of extra information or code to compensate for possible errors
- Genetic communication - communication of information in a form analagous to biological genes, such as in a sequential or additive fashion
- Hamming distance - the number of positions in two strings of equal length which have different corresponding symbols
- Hamming weight - the number of symbols in a string that are different from the zero symbol in the utilized alphabet
- Information entropy - the level of uncertainty associated with a random variable (often refers to the "Shannon entropy")
- Mutual information - occasionally called transinformation, the quantity that measures the mutual dependence of two random variables
- Rate distortion theory - the branch of information theory which explains lossy data compression and which determines the minimal amount of entropy that should be communicated over a channel
- Rate-distortion - the number of bits per data sample to be stored or transmitted and the amount of distortion in that sample
- Speech coding - the use of the data compression of digital audio signals to encode speech
