<p>The present invention discloses an method and device for amplitude calculating used for signal reconstruction, said method including that: according to channel information of Dedicated Physical Control Channel (DPCCH) demodulated by a receiving end, a first depolarization soft symbol of the DPCCH is calculated(101); according to channel information of Enhanced-Dedicated Physical Date Channel (E-DPDCH) demodulated by the receiving end, a second depolarization soft symbol of the E-DPDCH is calculated(102); according to the first depolarization soft symbol and the second depolarization soft symbol, a Bed/Bc amplitude table is looked up to obtain the amplitude of the signal to be reconstructed(103). The present invention enables increasing adaptability and accuracy of amplitude calculating, thus contributes to increase the accuracy of the signal reconstruction and improves the effect for interference cancellation. The problem that in the related technology the poor accuracy of the signal amplitude parameters results in the poor accuracy of the signal reconstruction which does not contribute to the interference cancellation can be avoided.</p> |
