    Abstract: Methods and apparatus for facilitating wireless communication using digital Quadrature Amplitude Modulation are disclosed. A mapping module electronic component of a wireless communication device utilizes a signal constellation for quadrature modulating a signal for transmission or quadrature demodulating a received signal. The signal constellation includes multiple constellation symbols and associated bit sequences. Specific signal constellations are disclosed. The signal constellations may be obtained through an optimization procedure which accounts for both phase noise and power amplifier nonlinearity.

    Abstract: This application discloses a method including a transmit end that generates and sends a physical layer protocol data unit (PPDU), and a receive end that receives the PPDU and parses the PPDU. An enhanced directional multi-gigabit (EDMG) modulation field in the PPDU includes a channel estimation field (CEF), the CEF includes a CEF sequence, and a length of the CEF sequence is m, where m is determined based on a quantity of bonding channels and a quantity of subcarriers included on a channel. When a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) technology is introduced into a 60 GHz WLAN standard, an applied CEF sequence included in a CEF can be determined, and DFT-S-OFDM transmission is further performed by using the CEF sequence. In this way, a PAPR of a WLAN system can be reduced while frequency division multiplexing for a plurality of users is supported.
