Abstract: Duplicated physical layer convergence protocol (PLCP) protocol data unit (PPDU) transmission is described for a wireless device with reduced peak-to-average power ratios (PAPR). One example includes obtaining a first sub-PPDU from to PPDU that includes a data field with data content. A second sub-PPDU may also be obtained by duplicating the PPDU including the data content of the PPDU. At least one of a phase rotation, a phase offset, or a phase ramp is applied to at least a portion of a second set of sub-carrier of a wideband channel. The first sub-PPDU is transmitted on a first set of sub-carriers of the wideband channel and the second sub-PPDU is transmitted on the second set of sub-carriers of the wideband channel.
