METHOD FOR UPDATING SINGULAR VALUE DECOMPOSITION OF A TRANSFER MATRIX

摘要

A method is disclosed for adaptively updating full or partial singular value decomposition (SVD) of a transfer matrix. The method employs orthogonal projections of known output and input vectors onto initial estimates of left and right singular vectors to compute corrections to the initial estimates of the singular vectors and singular values and adaptively generate updated estimates thereof. The method can be used for MIMO systems, including system of wireless MIMO communications employing adaptive transmitter and V- BLAST techniques.
