Decoder design method for real time high speed anti-interference coding

This invention provides a new method of a decoder design with real-time high speed anti-interference coding containing a coder and a decoder of anti-interference coding, in which the basic circuit ofcoder and decoder is a reverse course and FEC main circuit is owned by the decoder. It includes coidng monitor matrix, serial/parallel conversion, parallel/serial conversion, primary judgement circuit, detection circuit, detection and comparison circuit, and decoding monitor matrix. An important ideal of this invention is to directly analyze source information code element by a detecting matrix without error code.
