1. A method for reducing a peak to average power ratio of a signal comprising: assigning a phase factor to each of a plurality of vectors associated with the signal; calculating a first peak to average power ratio value of a combined signal comprising a linear combination of each of the plurality of vectors multiplied by a corresponding phase factor assigned to each of the plurality of vectors; and assigning a final phase factor to each of the plurality of vectors, wherein the final phase factor is assigned on a basis that the first peak to average power ratio of the combined signal will be minimized.
