Performance Analysis of IEEE 802.15.4g MR-OFDM with Frequency Offset
IEEE 802.15.4g Standard specifies multi-rate and multi-regional orthogonal frequency division multiplexing (MR-OFDM) physical layer, which supports principally outdoor, low-data-rate, wireless, smart metering utility network (SUN). Caused by Doppler frequency shift of fading channel, the inter-channel interference (ICI) arises in MROFDM system. In this paper, the degrading of performance due to ICI for detection of phase shift keying modulation signal is provided. It is derived that non-ideal properties for reception symbols are characterized by sampling offset and phase shift on subcarrier. Furthermore, the influence on data demodulation under different conditions is analyzed in detail. Simulation results are consistent with the theoretical analysis.
