Abstract
A method of wirelessly communicating is disclosed. The method comprises generating a plurality of tones for a wideband orthogonal frequency division multiplex symbol (), the tones including a plurality of contiguous zero-valued tones, inverse Fourier transforming the tones to a plurality of time-domain samples (), copying a plurality of the time-domain samples as a portion of a cyclic block (), the cyclic block () contiguous with the time-domain samples (), time-domain window filtering the time-domain samples () and the cyclic block () to form a portion of the wideband orthogonal frequency division multiplex symbol (), wherein the time-domain window filter () is a function Φ(k) having the property that Φ(k)+Φ(k+N) is about equal to a constant θ where Nis the number of tones, and transmitting the wideband orthogonal frequency division multiplex symbol ().
