Information About

Block Code




The main characterization of a block code is that it is a ''fixed length'' channel code (unlike source coding schemes such as Huffman Coding , and unlike channel coding methods like Convolutional Encoding ). Typically, a block code takes a ''k''-digit information word, and transforms this into an ''n''-digit codeword.

Block coding was the primary type of Channel Coding used in earlier Mobile Communication systems.
