Abstract
Systems, devices and methods for enhancing error correction decoding for communications using chirp spread spectrum are disclosed. A chirp signal having a plurality of chirps is received, a codeword is identified based on at least one of the plurality of chirps, a received signal strength indicator (RSSI) associated with at least a portion of the codeword is identified, at least one decoding threshold is adjusted based on the identified RSSI, and the codeword is decoded using the adjusted at least one decoding threshold.
