Abstract :
Extended Binary Phase Shift Keying (EBPSK) modulation with very high spectra efficiency is a hot research problem in the field of communication. This paper proposes an optimum design method of digital filters in EBPSK demodulation aiming at very tiny waveform difference, which is based on the minimum bit error rate (BER) criteria. Simultaneously, the inter symbol interference is considered as a constraint condition. Also the impulse filter proposed by Wu is used as comparison by computer simulation, the results illustrate that our proposed optimum method has better performance.
