Patent number: 11824579Abstract: A chirp spread spectrum (CSS) receiver may reject, based on multiple data alignment chirps that includes an attribute identifier that is a mismatch to one or more preconfigured identifiers, a message early and before fully receiving/decoding the message. The multiple data alignment chirps may enable usage of a larger range of IDs than a single chirp signal. A receiver may receive a sequence of training chirps for symbol alignment followed by multiple opposite chirps for data alignment. Training chirps may be processed through a fast-Fourier transform (FFT) and the resulting values accumulated until a threshold is exceeded. Using symbol alignment from the training chirps, the receiver may decode multiple opposite chirps that indicate data alignment and comprise an encoded identifier. The receiver may reject the message and terminate further message processing based on the encoded identifier being a mismatch to preconfigured identifiers or attributes indicated by the encoded identifier.Type: GrantFiled: December 31, 2021Date of Patent: November 21, 2023Assignee: Hall Labs LLCInventors: David R.

Patent number: 11736142Abstract: Data acquisition in a chirp spread spectrum (CSS) signal may use a data alignment indicator of a single down chirp signal or single upchirp signal. A receiver may receive part or all of a preamble comprising a sequence of training chirps for symbol alignment followed by a single opposite chirp for data alignment. Training chirps may be processed through a fast-Fourier transform (FFT), and the values from the FFT may be accumulated. The accumulated values may exceed a threshold for detection. The receiver may align, based on the received chirps of the preamble and exceeding the threshold, its symbol reception. Using this symbol alignment, the receiver may await a single opposite chirp after the sequence of training chirps. The single opposite chirp may indicate data alignment. Upon receipt of the opposite chirp, the receiver may start data acquisition based on chirps following the single opposite chirp.Type: GrantFiled: December 31, 2021Date of Patent: August 22, 2023Assignee: Sure-Fi, Inc.Inventors: David R.
