Abstract

Dual sub-carrier modulation (DCM) is introduced in high efficiency (HE) WLAN. DCM is a solution to deal with narrow band interferences and for range extension. DCM can introduce frequency diversity into OFDM systems by transmitting the same information on two subcarriers separated in frequency. If DCM is applied, then the transmitter modulates the same encoded bits onto two separated subcarriers with the same or different constellation mapping schemes. DCM suffers from a high peak-to-average power ratio (PAPR). In accordance with one novel aspect, a method of transmitting and encoding a HE PPDU frame with binary phase shift keying (BPSK) DCM and lower PAPR is proposed.
