Anti-jamming Performance of CCPR in FFH/BFSK Systems

摘要

Communication countermeasures technique is an important component of contemporary military wireless communication system. In this paper, an anti-jamming receiver, clipper cascaded product-combining receiver (CCPR) has been presented for the fast frequency-hopped binary frequency-shift- keying (FFH/BFSK) spread-spectrum communications system with two typical hostile jamming and the additive white Gaussian noise. Further analysis and simulation indicate that the system anti-jamming performance, using this method presented in this paper, could be improved about 10dB better than conventional product combining and self-normalizing combining when the signal-to-jamming ratio (SJR) less than -10dB. Furthermore, its low complexity makes it carry out easily.
