Abstract:
1. A non-transitory computer-implemented method for determining a path metric in a receiver by selecting N metrics among M metrics, where M>N≧1, the method comprising: determining, using a computer processor, M metrics P(i)=[b initializing, using a computer processor, two comparison values, P(i) determining, using a computer processor, a sum of j-th bit for M P(i)s, where j=0, 1, . . . , B−1, as shown: where sum(j) denotes the sum of j-th bit for M P(i)s, ‘˜’ denotes a bit inversion operation, ‘&’ denotes a bit AND operation, and ‘|’ denotes a bit OR operation; updating, using a computer processor, P(i) selecting, using a computer processor, at least one P(i) having a P(i)
