摘要
The invention regards to apparatus having a Nordstrom- Robinson code Decoder for decoding Nordstrom-Robinson code coded information, wherein a distance calculator (13) is adapted to receive inter-block interference cancelled vector (X) and intra-block interference compensated Nordstrom- Robinson code vector (S (i) ) from a interference canceller (10), to calculate the Euclidean distance between the two vectors (X, S(i) ), a decoder (14) is adapted to receive the Euclidean distances calculated by distance calculator (13) and to choose a minimum distance and its corresponding Nordstrom-Robinson code codeword and to output a decision Nordstrom-Robinson code vector, and a soft information calculator (15) is adapted to receive the Euclidean distances from distance calculator (13) and to calculate a log-likelihood ratio (LLR).
