ABSTRACT:
Aspects of a method and system for a delta quantizer for MIMO pre-coders with finite rate channel state information feedback may comprise quantizing a change in channel state information in a MIMO pre-coding system onto at least a first and a second codebook, each of which comprises one or more unitary matrices, using a cost function; and generating the at least first and second codebook based on at least the channel state information. The channel state information may be a matrix V and the cost function may be defined by the following relationship:f⁡(A)=(1N⁢∑j=1N⁢aj⁢⁢j2)where A is a matrix of size N by N and aijis element (i,j) of matrix A. One or more unitary matrices may be generated for the at least first codebook from at least a first set of matrices and a second set of matrices.
