Abstract: A method, apparatus, receiver, computer program and storage medium for joint detection are disclosed. The joint detection method includes categorizing interference signals based on level of interference so as to obtain a strong interference signal, cancelling the strong interference signal from a received signal, and performing a joint detection by utilizing a matched filtering result of a remaining signal. In one embodiment, it is to firstly determine whether a strong interference codes corresponding to an intra-frequency adjacent cell exists in an active code list or not, recovering a strong interference signal transmitted by a Node B if the strong interference codes exists, applying an interference cancellation to a received signal received by a receiver so as to obtain a matched filtering result of a remaining signal derived by subtracting the strong interference signal from the received signal, performing a joint detection by utilizing the matched filtering result of the remaining signal, and outputting a demodulated result. In at least one embodiment, the computation complexity of the joint detection is reduced, and the accuracy of the joint detection is improved.
