<P>PROBLEM TO BE SOLVED: To facilitate constructing unitary matrices that may be utilized in linear precoding for multiple-input multiple-output (MIMO) wireless communication systems. <P>SOLUTION: Each unitary matrix may be generated by combining (e.g., multiplying) a diagonal matrix with a Discrete Fourier Transform (DFT) matrix. The unitary matrices are utilized to provide feedback related to a channel and/or control transmission over a channel based upon obtained feedback. <P>COPYRIGHT: (C)2012,JPO&INPIT |
