Channel coding Definition

Channel coding Definition   A coding technique is described which improves error performance of synchronous data links without sacrificing data rate or requiring more bandwidth. This is achieved by channel coding with expanded sets of multilevel/phase signals in a manner which increases free Euclidean distance. Soft maximum–likelihood (ML) decoding using the Viterbi algorithm is assumed. … Read more
