Abstract:
1. A joint detection method comprising: determining if a number of original active codes corresponding to a cell and intra-frequency adjacent cells exceeds a first threshold; if the number of the original active codes is beyond the first threshold and one or more strong interference codes exist among active codes corresponding to the intra-frequency adjacent cells, obtaining a number of first active codes of the original active codes excluding the one or more strong interference codes, wherein the number of the first active codes does not exceed the first threshold, and wherein a ratio of a power of each of the one or more strong interference codes to a power of an active code of a user exceeds a second threshold; applying, based on the one or more strong interference codes, an interference cancellation to a received signal to obtain a matched filtering result of a remaining signal excluding a strong interference signal corresponding to the one or more strong interference codes; and performing a joint detection by utilizing the first active codes and the matched filtering result of the remaining signal to obtain a first joint detection result.
