🛜 Golay Code error correction scheme for LoRaWAN systems was described. GFSK modulation (and demodulation) scheme was implemented in an AWGN channel. Encoding and decoding this model using the binary Golay Codes was done which gives a lower BER. The BER curves have been plotted for varying SNR.

GFSK modem (BT=0.5, 125 kbps) implemented in SystemVerilog on Xilinx Artix-7 — full TX/RX signal chain with Gaussian FIR, NCO FM modulation, Gardner timing recovery, and live BER measurement over UART.
