DETECTION METHOD USING YI ALGORITHM AND YI DETECTOR

摘要

In the field of communications technologies, embodiments of the present invention provide a detection method using a YI algorithm and a YI detector, so as to solve the technical problem of poor detection performance caused by signal environment variation in the prior art. In the embodiment of the present invention, parameters are obtained according to a received signal; a level threshold at each level starting from a level corresponding to a tailbits value is obtained according to the parameters, and validity of at least one node at the level is determined according to the level threshold, where the level is the same as a level of the level threshold; and a detection identifier is output according to the validity. The embodiment of the present invention is mainly applied to a scenario of detection using thresholds.
