Patent attributes
A method of wirelessly communicating is disclosed. The method comprises generating a plurality of tones for a wideband orthogonal frequency division multiplex symbol (310), the tones including a plurality of contiguous zero-valued tones, inverse Fourier transforming the tones to a plurality of time-domain samples (312), copying a plurality of the time-domain samples as a portion of a cyclic block (314), the cyclic block (314) contiguous with the time-domain samples (312), time-domain window filtering the time-domain samples (312) and the cyclic block (314) to form a portion of the wideband orthogonal frequency division multiplex symbol (310), wherein the time-domain window filter (350) is a function Φ(k) having the property that Φ(k)+Φ(k+Nfft) is about equal to a constant θ where Nfft is the number of tones, and transmitting the wideband orthogonal frequency division multiplex symbol (310).
