1. A method for wireless communications, comprising:

  • constructing a short training field (STF) sequence with a repetition period by using STF symbol values associated with the IEEE 802.11n standard, whereinthe STF symbol values cover at least a portion of bandwidth of a first size, andeach of the STF symbol values is repeated one or more times for different subcarriers;

    rotating phases of symbols of the STF sequence per bandwidth of the first size in an effort to reduce a peak-to-average power ratio (PAPR) during transmission of the STF sequence; and

    transmitting the STF sequence over a wireless channel by utilizing a bandwidth of a second size.
