This repository is a GNU Radio out-of-the-module (OOT) implementation of the LoRa physical layer. It provides a comprehensive set of signal processing blocks for transmitting and receiving LoRa signals, including channel coding (Hamming), interleaving, whitening, CRC, header processing, modulation, demodulation, and frame synchronization. The module is designed for use with GNU Radio 3.10+ and includes hierarchical blocks for quick assembly of transmitter and receiver flowgraphs in GNU Radio Companion or Python. It also features a simulation framework for performance evaluation (BER/FER vs SNR) and has been validated with USRP hardware and commercial LoRa transceivers. The code is modular, well-documented, and actively maintained, with recent updates adding support for lower spreading factors (SF 5-6) and improved soft-decision decoding.
