FIELD: data processing.
SUBSTANCE: invention relates to data transmission. According to the invention, there is provided a method of encoding and decoding data using an error control code having a codebook G. Codebook G is the code sub-book of the codebook P. Each codeword g in the sub-codebook G has an autocorrelation amplitude that is different from and higher than each correlation amplitude between g and each of the other codewords in the sub-codebook G.
EFFECT: when using the code of the Reed-Muller codebook P, the use of G instead of P reduces the probability of having more than one maximum correlation amplitude when calculating the incoherent solution metric during decoding.
