Claim Text:
1. A joint detection method for a Direct Sequence-Code Division Multiple Access device, the joint detection method comprising: determining whether a strong interference code corresponding to an intra-frequency adjacent cell of a servicing cell of the device exists in an active code list by determining if a ratio of a first power to a second power is beyond a first threshold, wherein the first power comprises a power corresponding to an interference code, and wherein the second power comprises a power corresponding to an active code of the device; if the strong interference code exists on the active code list, recovering a strong interference signal corresponding to the strong interference code; applying an interference cancellation to a received signal by cancelling the strong interference signal from the received signal to obtain a remaining signal; obtaining a matched filtering result of the remaining signal; and performing a joint detection by utilizing the matched filtering result of the remaining signal to output a demodulated result.
