Method and system for an efficient channel quantization method for mimo pre-coding systems

Abstract

Aspects of a method and system for an efficient channel quantization method for MIMO pre-coding systems may include quantizing channel state information in a MIMO pre-coding system onto a codebook, which comprises one or more unitary matrices, using a cost function; selecting a quantization function that enables the quantizing based on a number of receive antennas and a number of transmit antennas associated with the MIMO pre-coding system; and selecting the cost function from a set of cost functions based on the number of receive antennas and the number of transmit antennas. The channel state information may be a matrix Ĥ. The set of cost functions may comprise function f(A), which may be defined by the following relationships: f  ( A ) = ∑ i = 1 N   ∑ j = 1 , j ≠ i N    a i , j  2   and / or   f  ( A ) = ∑ i = 1 N   ∑ j = 1 , j ≠ i N    a i , j  2 - ∑ i = 1 N   a i , i where A is a matrix of size N by N and aij is element (i,j) of matrix A.
