Process and system for encoding a word of original information having k bits to improve the efficiency of coding and the use of bandwidth of a channel.Process and system for improving the efficiency of coding and the use of bandwidth of a telecommunications channel using orthogonal codes.Process and system for decoding a code word received on a composite of Walsh demodulada telecommunications channel using orthogonal codes for a word of original information.Processes to encode a word of original information having m times k bits, [log ~ 2 ~ (2 ^ 2K + 1) ^ + 2 ~ k - 1 ~)] bits of binary information.And 2K bits to improve the efficiency of coding and the use of bandwidth of a telecommunications channel using orthogonal codes.Process and system for decoding a set of Walsh code word appended demodulada received on a telecommunications channel using orthogonal codes in a word of information orIginal, and systems to encode a word of original information with 2K bits.And 2K + 1 and m times k bits and binary information to improve the efficiency of coding and the use of bandwidth of a telecommunications channel using orthogonal codes.A system and process to allow variable rates and information and better performance of error using orthogonal or near orthogonal encoding is disclosed.This is achieved by simultaneous transmission of two or more words of Walsh code from a given set of orthogonal code and / or the transmission of multiple orthogonal codes more words.Short sequ00b3encialmente, so that their combined lengths equal to the code word original.It must be emphasized that the present invention can be used with any set of orthogonal or near orthogonal code.
