APPARATUS AND METHOD OF MATRIX DECOMPOSITION IN TD-SCDMA BASEBAND PROCESS

摘要

An apparatus and a method of the matrix decomposition. The apparatus comprises: an A-matrix data buffer for storing the A-matrix plural data that the real part and the imaginary part are 16 bits respectively; a G-matrix data buffer for storing the data which the real part and the imaginary part of real number of the G-matrix non-diagonal element and the real number of the diagonal element are 16 bits and 32 bits respectively; a control circuit unit for calculating the size of A-matrix based on the dimension number of the matrix sent from the system dispatch unit and generating the address control message of the A-matrix data buffer and the G-matrix data buffer; and a account circuit unit of extract and inversion for accounting the extract and inversion of the diagonal element of the G-matrix according to the time sequence request.
