<P>PROBLEM TO BE SOLVED: To provide techniques for properly rotating and transmitting multidimensional constellations in wireless communication systems. <P>SOLUTION: A method of rotating a multidimensional constellation may include constructing a first rotation matrix; constructing a second rotation matrix; applying orthogonality constraints to the first and second rotation matrices; selecting an optimizing rotation matrix from the first and second rotation matrices; and rotating the multidimensional constellation using the optimizing rotation matrix. The construction of the first and second rotation matrices may include constructing a first column including first matrix elements based on the number of axes in the multidimensional constellation, and additional columns including permutations of the first matrix elements. <P>COPYRIGHT: (C)2012,JPO&INPIT |
