ABSTRACT:
A method for optimizing phase factors in partial transmit sequence orthogonal frequency division multiplexing system. The method includes initializing sub-block signals by applying an initial phase factor to the sub-block signals in all sub-blocks; setting a reference peak value with a peak value of a signal formed by combining the sub-block signals; selecting a phase value that minimizes the peak value of an output signal as the phase factor of each sub-block by applying a next phase value to each sub-block signal as the phase factor, and repeating this with respect to the remaining available phase values.
