FFT-based clipper receiver for fast frequency-hopping spread-spectrum system
This paper presents the performance analysis of a binary frequency-shift keying fast frequency-hopping spread-spectrum (BFSK/FFH SS) system equipped with a fast Fourier transform (FFT) processor and a clipper. The FFT-based clipper receiver provides an alternative approach to suppress partial-band jamming (PBJ) in discrete-time domain. The analytical expression for the probability of bit error is obtained and numerical results show that the performance of FFT-based receiver is better than that of the linear-combining receiver and comparable to that of the clipper receiver.
