Title:
APPARATUS AND METHOD OF MATRIX DECOMPOSITION IN TD-SCDMA BASEBAND PROCESS
Document Type and Number:
WIPO Patent Application WO/2008/092298
Kind Code:
A1
Abstract:
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.
