摘要： 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.
摘要翻译：本发明提供了一种用于信号重建的幅度计算方法和装置，其特征在于，该方法包括：根据接收机解调的DPCCH信息，计算专用物理控制信道（DPCCH）的第一去极化软符号（ 101）; 根据由接收机（102）解调的E-DPDCH的信息，计算增强专用物理数据信道（E-DPDCH）的第二去极化软符号; 并且查找Bed / Bc幅度表以根据第一去极化软符号和第二去极化软符号（103）获得要重构的信号的幅度。本发明可以提高幅度计算的适应性和准确率，有利于提高信号重建的准确性，提高干扰消除的性能，解决了现有技术中信号幅度参数精度差的问题，从而信号重建的精度可能相当差，这对于消除干扰是不利的。
