ABSTRACT:
A method for optimizing a transmission format of a reference signal is disclosed. A first matrix is provided. A second matrix is computed from the first matrix. A derivative of a function of the second matrix is defined. Iterates of the function are obtained. A function of the second matrix is determined. An optimum value of the first matrix is calculated.
