PROBLEM TO BE SOLVED: To provide a method for generating channel quality feedback information for a communication channel of a communication system. SOLUTION: In this method, the channel quality feedback information is generated in terms of quantized eigenvectors calculated from an eigenvalue decomposition that uses a channel matrix and an eigenvalue matrix to generate bounded and quantized eigenvectors. The channel correlation matrix and the eigenvalue matrix are obtained from a channel matrix formed from channel measurements of various signal parameters of signals transmitted over a communication channel. The eigenvalue decomposition uses the channel correlation matrix, the elements of the eigenvalue matrix and state relationships between elements of the channel correlation matrix to form the bounded and quantized eigenvectors. Because the elements of the bounded and quantized eigenvectors can be expressed in terms of the elements of each other, not all elements of the bounded and quantized vectors need be transmitted over the communication channel resulting in efficient use of the communication channel.
