Claim Text:
1. A wireless communication device comprising: a communication interface; and a processor, at least one of the processor or the communication interface configured to: generate an orthogonal frequency division multiplexing (OFDM) packet that includes at least one field having information modulated on a plurality of sub-carriers, wherein the plurality of sub-carriers has a tapered power profile such that a first sub-carrier located at a first edge of the plurality of sub-carriers and a second sub-carrier located at a second edge of the plurality of sub-carriers have relatively less power than at least one other sub-carrier of the plurality of sub-carriers that is located between the first sub-carrier and second sub-carrier, wherein first average power of a first field of the OFDM packet is relatively greater than second average power of a second field of the OFDM packet; and transmit the OFDM packet to another wireless communication device.
