On the Use of Polar Code for LoRa PHY

Abstract

LoRa (long range) PHY adopts simple hamming codes with maximum one-bit error correction capacity, which is one of the main causes of poor performance in fading environments. As one approach to improve performance in fading environments, in this paper, we will investigate the use of a polar code for LoRa. Specifically, through computer simulations, we will compare the performance gain in Rician fading channels according to the application of a polar code with code rate 0.5 instead of the original (8,4) hamming code in LoRa PHY.
