<p>A method and device for parallel interference cancellation based on control channel ,the kernel of the invention is: by means of a base station performing the despread, incorporation, and judgment for received signal in each user's DPCCH, obtaining demodulation judgment information; then according to the pilot frequency information in the received DPCCH of each user and the obtained demodulation judgment information ,reconstituting the received signal in each user's DPCCH, and performing the parallel interference cancellation procedure for the received user base band data based on the reconstituted signal. By the present invention ,only one demodulation procedure is needed, so the realization is easier and the dissipative realization resource is less; and because the TPC signal based on time slot level reconstitutes the received signal in the user's DPCCH, the waiting time delay of the storage of base band data and the demodulation procedure of service channel could be reduced; furthermore through the present invention cancels some interference of user's DPCCH, the receibe SNR of the service channel is improved, so the capacity and coverage capability of the whole selfinfection system are improved.</p> |
