A method and an apparatus for amplitude calculation used for signal reconstruction are provided by the present invention, wherein the method comprises: calculating a first depolarized soft symbol of a Dedicated Physical Control Channel (DPCCH) according to information of the DPCCH demodulated by a receiver (101); calculating a second depolarized soft symbol of an Enhanced Dedicated Physical Data Channel (E-DPDCH) according to information of the E-DPDCH demodulated by the receiver (102); and looking-up a Bed/Bc amplitude table to obtain an amplitude of a signal to be reconstructed according to the first depolarized soft symbol and the second depolarized soft symbol (103). The present invention can improve the adaptability and accuracy rate of amplitude calculation and facilitates to improve the accuracy of signal reconstruction and improve the performance of interference cancellation, which solves the problem in the related art that the accuracy of signal amplitude parameters is rather poor, and thereby the accuracy of signal reconstruction may be rather poor, which is disadvantageous for cancelling interference. |
