Abstract: The present invention relates a method, apparatus, receiver, computer program for joint detection. In the method, it is firstly determined if whether a number of original active codes is beyond a predefined threshold or not, and when the number of the original active codes is beyond the predefined threshold and a strong interference code exists in the active codes corresponding to intra-frequency adjacent cells, it is to apply an interference cancellation to a receive signal, cancel MAI caused by a strong interference signal corresponding to the strong interference code, and perform a joint detection by utilizing a matched filtering result of a remaining signal after the interference cancellation for the joint detection. According to at least one embodiment of the present invention, when there is large interference in the intra-frequency adjacent cells and the number of the active codes is beyond a maximum threshold, the joint detection performance is improved.
