ABSTRACT:
A method for bounded distance decoding of symbols received in transmission when the original symbols belonged to a Block code featuring series of symbols forming legitimate codewords whose metric distance from the received transmission is measured in Square Euclidean Distance (SED), when the maximum number of errors per word is upward bound by d-1; in which the Block code can be divided into subsets which will each define the entire codeword; and in which the maximum number of errors in at least one subset is one. The method includes dividing the received symbols into a number of blocks per codeword and decoding each block separately and simultaneously with regard to a maximum of one error present in each block. The solution of the decoder is the legitimate codeword with the lowest overall metric distance (SED) from the received transmission.
