APPARATUSES FOR WIRELESS COMMUNICATION IN SUB GIGAHERTZ BANDS ENSURING SPECTRAL FLATNESS

摘要

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.
