Abstract: Apparatuses for wireless communication are provided. The apparatus includes a processor configured to generate a packet for transmission via a wireless signal. The packet is generated for transmission over a bandwidth of 1 MHz using at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising 32 subcarriers described by indices from -16 to 15, wherein each of the 32 subcarriers has an average constellaton enrgy. The apparatus further includes a transmitter configured to transmit the packet via the wireless signal such that each average constellation energy for subcarries having indices of -8 to -1 and 1 to 8 deviates no more than +-4 dB from an overall average of the average constellation energies over subcarriers having indices of -8 to -1 and 1 to 8, and each average constellation energy for subcarries having indices of -13 to -9 and 9 to 13 deviates no more than +4/-6 dB from the overall average.

Abstract: Systems, methods, and devices for wireless communication are provided. In one aspect, an apparatus for wireless communication is provided. The apparatus includes a processor configured to generate a packet for transmission via a wireless signal. The packet is generated for transmission over a bandwidth of 1 MHz using at least one orthogonal frequency-division multiplexing (OFDM) symbol. The apparatus further includes a transmitter configured to transmit the packet via the wireless signal having a power spectral density. The power spectral density within ±0.45 MHz of a center frequency of the wireless signal is at a first power spectral density level. The power spectral density between 0.45 MHz and 0.6 MHz from the center frequency of the wireless signal and between -0.45 MHz and -0.6 MHz from the center frequency of the wireless signal is less than the first power spectral density level. The power spectral density between 0.6 MHz and 1 MHz from the center frequency of the wireless signal and between -0.6 MHz and -1 MHz from the center frequency of the wireless signal is less than -20 dBr with respect to the first power spectral density level. The power spectral density between 1 MHz and 1.5 MHz from the center frequency of the wireless signal and between -1 MHz and -1.5 MHz from the center frequency of the wireless signal is less than -28 dBr with respect to the first power spectral density level. The power spectral density of greater than ±1.5 MHz from the center frequency of the wireless signal is less than -40 dBr with respect to the first power spectral density level.
