FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication methods. The invention provides a method of encoding and decoding data using an error control code contained in a codebook G. The codebook G is a sub-codebook of a codebook P. Each codeword g in the sub-codebook G has an autocorrelation amplitude which is different from and higher than each correlation amplitude between g and each of the other codewords in the sub-codebook G. In one specific version in which the codebook P is that of a Reed-Muller code, using G instead of P reduces the likelihood of the presence of more than one maximum correlation amplitude when computing the non-coherent decision metric during decoding.
EFFECT: wider field of use.
