Abstract:

This paper proposes novel two carrier frequency offset (CFO) estimation schemes to introduce inexpensive oscillators and operate under mobile multipath environments in wide area Wi-SUN systems based on IEEE 802.15.4g. One of the proposed schemes using a moving average low-pass filter (LPF) can compensate CFO within ±20 ppm at 920 MHz completely with simple configuration under condition of mobile and multipath fading environment. The second proposed scheme using the same LPF of the first scheme and artificially designed frequency offset can compensate larger CFO within ±30 ppm at 920 MHz.
