This disclosure describes methods, apparatus, and systems related to a low peak-to-average power ratio (PAPR) long training field (LTF) sequences system. A device may determine a wireless communication channel with a first device in accordance with a wireless communication standard, the wireless communication channel having one or more streams. The device may determine one or more common sequences between the one or more streams. The device may generate a high efficiency preamble in accordance with a high efficiency communication standard. The device may generate one or more LTF sequences included in the preamble based on the one or more common sequences and one or more codes. The device may cause to send the high efficiency preamble over the wireless communication channel.
