- This paper proposes an optimized multi-bit digital FSK receiver robust to large carrier frequency offset (CFO)toward recently emerging long-range WPAN standards. Due to a short preamble length and strict BERrequirements, we design a simple multi-bit digital demodulator combined with CFO estimator which guaranteesthe target BER performance. Simulation results verify that the proposed FSK receiver achieves CFO-free BERperformance with the short preamble and satisfies the BER requirement by the recent WPAN applications.
