A GFSK transceiver for IEEE Std. 802.15.4g used in China

This paper details on the design of GFSK (Gaussian frequency shift keying) transceiver with low-complexity high-performance low power consumption, which is compliant with IEEE Std. 802.15.4g used in China. In this architecture of transceiver, the capability of suppression phase noises is improved by employing fractional-N divider synthesizer with the 3rd-order sigma delta modulator, and the power consumption is also saved for using a discrete-time quadricorrelator with simple stucture in demodulator. Meanwile, system simulation results show, corresponding to other transceivers, this architecture is optimized and presents a good tolerance for carrier frequency offset within ± 50KHz.
