TRANSMITTER, RECEIVER AND TELECOMMUNICATION METHOD FOR IMPROVING THE FUNCTIONING OF FEEDER EQUALIZERS IN TELECOMMUNICATION SYSTEMS USING ERROR CORRECTION

摘要

This invention relates to digital telecommunications. / P P The use of a set of encoders and decoders 206-1, ... 206-M; 216-1, ... 216-M in the transmitter and receiver of a telecommunication system provides the combined advantages of feedback and decision equalization and error correction coding. The set of coders and decoders are used to interleave the data symbols, so that each coder and decoder works on a symbol on M, denoting by M the number of coders or decoders. A judicious choice of M reduces the effects of noise and error propagation. / P P Applications to telephone modems. / P
