A method for generating channel quality feedback information in terms of quantized eigenvectors calculated from an eigenvalue decomposition that uses a channel matrix and an eigenvalue matrix to generate quantized and bounded 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 the communication channel. The eigenvalue decomposition uses the elements of the channel correlation matrix, the elements of the eigenvalue matrix and conditional relationships between elements of the channel correlation matrix to calculate the quantized and bounded eigenvectors. Because the elements of the quantized bounded eigenvectors can be expressed in terms of each other, not all elements of the quantized bounded vectors need be transmitted over the communication channel resulting in efficient use of the communication channel. |
