Abstract
A novel acceptance criterion that is less stringent than previous criteria is developed. The criterion accepts the codeword that is closest to the received vector for many cases where previous criteria fail to accept any codeword. As a result, the performance of generalized minimum distance (GMD) decoding is better if the new criterion is used. For M -ary signaling, the weights used in GMD decoding are generalized to permit each of the possible M symbol values to have a different weight
