ABSTRACT:
In a method for parallel interference cancellation (PIC) in a mobile communication system, every user signal is processed through multiple stages of PIC to remove multiple address interference (MAI) partly. In any middle stage and final stage, multipath de-spread is made for output signal of last stage to obtain a multipath de-spread result of this stage. The multipath de-spread result of this stage and that of the last stage of a user are combined to obtain a combined multipath de-spread result, which is sent to next stage when it is in a middle stage. Channel estimation and multipath combination are made based on the combined multipath de-spread result to obtain an output of the user. A PIC device is provided for the method. The method and the PIC device may raise SNR of the de-spread result of each user.
