GENERATION AND APPLICATION OF A SUB CODEBOOK OF AN ERROR CONTROL CODING CODEBOOK

摘要

GGPGPGPThere is provided a method of encoding and decoding data using an error control code having a codebook . The codebook is a sub codebook of a codebook . 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 . In one specific embodiment in which the codebook is that of a Reed Muller code using instead of reduces the likelihood of the presence of more than one maximum correlation amplitude when computing the non coherent decision metric during decoding.
