Abstract

Abstract

Theory and realization of FY-2 B satellite original nephogram demodulator is introduced in this paper. By using Decision-feedback loop and programmable bit synchronizer, the demodulator has the advantage of quick lock, wide lock band and low bit error rate. This device has already been field tested and now using in CDAS Satellite station.
