Low peak-to-average power ratio long training field sequences
First Claim
1. A device, comprising:
- at least one memory that stores computer-executable instructions; and
one or more processors configured to access the at least one memory, wherein the one or more processors are configured to execute the computer-executable instructions to;
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;
determine one or more common sequences between the one or more streams;
generate a preamble in accordance with a high efficiency communication standard;
generate one or more long training field (LTF) sequences included in the preamble based at least in part on the one or more common sequences and one or more codes;
determine a peak-to-average power ratio (PAPR) based at least in part on the one or more LTF sequences;
cause to send the preamble over the wireless communication channel;
determine a first PAPR value for a first stream of the one or more streams based at least in part on a first Hadamard code;
determine a second PAPR value for a second stream of the one or more streams based at least in part on a second Hadamard code;
sort the first PAPR value and the second PAPR value from low to high; and
define a sequence for the one or more LTF sequences based at least in part on sorting the first PAPR value and the second PAPR value.

Abstract
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.

8. A non-transitory computer-readable medium storing computer-executable instructions which, when executed by a processor, cause the processor to perform operations comprising:
-
determining a wireless communication channel with a first device in accordance with a wireless communication standard, the wireless communication channel having one or more streams; determining one or more common sequences between the one or more streams; generating a preamble in accordance with a high efficiency communication standard; generating one or more long training field (LTF) sequences included in the preamble based at least in part on the one or more common sequences and one or more codes; determining a peak-to-average power ratio (PAPR) based at least in part on the one or more LTF sequences; causing to send the preamble over the wireless communication channel; wherein determining the PAPR comprises; determining a first PAPR value for a first stream of the one or more streams based at least in part on a first Hadamard code; and determining a second PAPR value for a second stream of the one or more streams based at least in part on a second Hadamard code; and wherein the computer-executable instructions cause the processor to further perform operations comprising; sorting the first PAPR value and the second PAPR value from low to high; and defining a sequence for the one or more LTF sequences based at least in part on sorting the first PAPR value and the second PAPR value. - View Dependent Claims (9, 10, 11, 12)
