Abstract

We present a new communication method at low frequency (LF) of applying a wireless communication system using chirp spread spectrum (CSS) technique. First, we introduce the CSS system, including the modulation and demodulation technique. Then analyze property of LF atmospheric noise in time and frequency domain based on the real atmospheric noise data acquired by superconducting quantum interference device (SQUID) sensor. Finally, we perform the simulation of the CSS system performance in additive white Gaussian noise (AWGN) channel and atmospheric noise channel to verify the feasibility of the application in LF communication system.
