Abstract
Hypothesis tests, such as maximum likelihood detections, are executed on symbol sequences received by, for example, a user equipment (UE) in a communication system. The hypothesis tester checks a received sequence against a group of predetermined sequences that possibly could have been sent to the UE. For received sequences that are matched or not matched by the hypothesis tester with high confidence, complete decoding, for example, with a Viterbi decoder, is not necessary. Instead, complete decoding is used as a “tie-breaker” for those sequences which the hypothesis tester cannot match or not match with desired confidence levels.
