Abstract :
Bluetooth is a short-range communication standard which employs Gaussian frequency shift keying (GFSK). The design of low-complexity and high-performance receivers for Bluetooth systems is a challenging task. In this paper, we develop an optimized differential GFSK demodulator and investigate the phase wrapping issue in its implementation. Simulation results show bit-error-rate (BER) performance improvement in comparison with conventional differential demodulators. We also compare our proposed demodulator with other existing alternatives in terms of BER performance and complexity.
