Patent ID: 8472537

Claim:
A wireless communications device using a multi-carrier modulation communication signal, the device comprising: an antenna; a transceiver coupled to said antenna; and a controller operable with said transceiver and being configured to reduce the peak-to-average power ratio (PAPR) of a signal field symbol in the multi-carrier modulation communication signal by at least transmitting information using a frame format comprising a header and a data field, the header having a signal field and a service field each having a plurality of bits, the plurality of bits of the signal field including data rate bits, a reserved bit and data length bits and defining the signal field symbol, and the data field including payload bits and pad bits, and selectively changing at least the header bits to generate the signal field symbol including setting the data length bits to result in the signal field symbol with a reduced PAPR, using filler bits as pad bits to adjust for the set data length, and setting the service field bits to indicate a correct data length.
