Abstract
The device, system and method reduce the peak-to-average power ratio (PAPR) of a signal field symbol in a multi-carrier modulation communication signal. The device includes an antenna, a transceiver coupled to the antenna, and a controller to cooperate with the transceiver and being configured to reduce the PAPR of the signal field symbol in the multi-carrier modulation communication signal. The controller is configured to transmit information using a frame format including 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 defining the signal field symbol. The controller selectively changes at least the header bits to generate the signal field symbol with a reduced or lowest PAPR.
