Abstract

A symbol generator (804) generates a time-domain discrete multi-tone symbol (810). A magnitude comparator (812) compares the magnitude of the time-domain discrete multi-tone symbol (810) with a magnitude threshold. When the magnitude of the time-domain discrete multi-tone symbol (810) compares unfavorably to the magnitude threshold, a magnitude adjusting symbol (816) is added to the time-domain discrete multi-tone symbol (810) such that the magnitude of the time-domain discrete multi-tone symbol (810) is reduced, thereby reducing the peak-to-average requirements (PAR).
