Abstract:
1. A method of coding and/or decoding binary data for wireless transmission, particularly for radio transmitted data, characterised in that a sequence of binary data, introduced at the entry to the coding machine with a class N coder (KOD) comprising a register (REG), a comparator (COMP) and a counter (CITN), wherein N is a number greater than or equal to 3, is separated into a sequence of binary data of the same value, so that the length of each such sequence is not less than one and not more than N, and so that the binary values of the data introduced at the entry to the coder (KOD) are compared with the value last received and recorded in it, the lengths of the same sequences at this entry are read up to the number N and, after reading to N, a sequence of binary data of a value opposite to the value at the entry to the coder (KOD) is inserted, this inserted data sequence having a length M, where M is a number greater than or equal to one and less than N, at the same time the value recorded in the register (REG) is inverted and the length of the inserted sequence M is entered into the counter, while with each change in the register (REG) of the recorded value of the last bit received, registration of the length of the data sequence from the counter (CITN) to the buffer (BUF) is initiated, wherein the lengths of the sequences of binary data are interpreted as binary impulses of length X 1 , X 2 . . . X N , wherein X 1 to X N are time constants of mutually different values, assigned to various lengths of sequences of the same binary data.
