Low-density parity-check (ldpc) codeword selection for ultra-wideband (uwb)

A method of ultra-wideband (UWB) communication, the method comprising:

• receiving, at a receiving UWB device, a payload having one or more codewords transmitted via UWB communication by a transmitting UWB device, the payload having a number of information bits;
• selecting, at the receiving UWB device and based on the number of information bits, a codeword length from a selection of available codeword lengths with which to decode the payload using a low-density parity-check (LDPC) decoding scheme, wherein the selection of available codeword lengths include a first codeword length, a second codeword length, and a third codeword length, wherein the third codeword length is longer than the second codeword length, which is longer than the first codeword length;
• and
• decoding, with the receiving UWB device, the payload using the selected codeword length.

A transmitting ultra-wideband (UWB) device, comprising:

• a transceiver;
• a memory;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
• determine a number of information bits of a payload to communicate via UWB;
• select, based on the number of information bits, a codeword length from a selection of available codeword lengths with which to encode the payload using a low-density parity-check (LDPC) encoding scheme, wherein the selection of available codeword lengths include a first codeword length, a second codeword length, and a third codeword length, wherein the third codeword length is longer than the second codeword length, which is longer than the first codeword length;
• and
• transmit, via the transceiver, the payload using one or more codewords having the selected codeword length.
