The present invention relates to the encoding and decoding. respectively, of serial data, using block codes. Encoding of a serial bit stream of input data in groups of N bits, so-called words (O), to serial output data in groups of 2N bits, so-called code words (KO), is preferably carried out by a logic circuit in a manner such that N of the 2N bits in the code words (KO) are comprised of the N bits input data, unchanged or inverted, and remaining bits in the code words (KO) are determined so that, seen statistically, the code words (KO) will include approximately as many zeros as ones, such that each code word (KO) will be unique for each word (O), and such that at least one of the code words (KO) will remain unique even in bit stream shifting processes. Decoding includes further encoding in a similar logic circuit and comparison of the incoming code words with the code words encoded in the logic circuit, in a predetermined manner.
A method of encoding a serial bit stream of input data in groups of N bit data words of any data content to output codewords of 2N bits, comprising:
A signal transmitting a digital bit stream encoding a series of data words of any data content as an encoded bit stream of codewords comprising:
A method of high speed coding of any data stream input as a series of data words of any data content into a stream of codewords, said method comprising:
