摘要： Systems and methods for performing low-density parity-check (LDPC) coding may include a wireless communication device that determines a count of a plurality of information bits. The wireless communication device may select a codeword length according to the count. A LDPC encoder of the wireless communication device may generate a codeword for the plurality of information bits, the codeword having the codeword length. The wireless communication device may transmit the codeword to an LDPC decoder of another wireless communication device.

摘要： Systems and methods for configuring reduced repetitions for ultra-wideband (UWB) physical layer headers may include a first UWB device that generates a packet including a first header and a second header. The first header may include a plurality of bits indicating a data rate and an encoding scheme of a payload of the packet. The first UWB device may transmit the packet to a second UWB device. The second UWB device may receive and decode the packet according to the encoding scheme and the data rate.

摘要： Systems and methods for selecting preamble codes for ultra-wideband (UWB) data transmissions include a device which selects a first preamble code of a plurality of preamble codes for a data transmission sent via at least one UWB antenna to a second device. Each of the plurality of preamble codes may have a sidelobe suppression ratio of at least 12 dB with respect to another one of the plurality of preamble codes. The device may transmit the data transmission including the first preamble code via the UWB antenna to the second device.

摘要： Systems and methods for data transmission within the ultra-wideband ranging protocol include a first UWB device which determines a transmission block comprising a plurality of rounds each representing a period of time. The first UWB device performs a first wireless communication to perform ranging between the first UWB device and a second UWB device, within a first round of the plurality of rounds. The first UWB device may perform a second wireless communication to communicate data between the first UWB device and the second UWB device, which may be within the first round or a second round.
