Abstract:
1. A method for optimizing a transmission format of a reference signal, the method comprising: providing a first matrix; computing a second matrix from the first matrix; defining a derivative of a function of the second matrix; obtaining iterates of the function of the second matrix; determining, by a processor, the function of the second matrix using the derivative of the function of the second matrix and the iterates; calculating, by the processor, an optimum value of the first matrix using the iterates of the function of the second matrix, wherein the optimum value of the first matrix minimizes the peak-to-average power ratio (PAPR) of a transmit signal; and transforming a plurality of data symbols to be sent contemporaneously with one or more reference signals using the optimum value of the first matrix.
