摘要：
A novel universal demodulator for remote sensing satellites is proposed and implemented in this paper. Compared with traditional multiple-function demodulator, this novel demodulator is much simpler mainly due to using a kind of new Intermediate Frequency (IF) filter and a programmable bit synchronizer. The new IF filter can accomplish the function which will be done by the IF filter and the base band filter in the traditional multiple-function demodulator, while the programmable bit synchronizer can synchronize different bit streams with different transmission rates. The demodulator has already been field tested with satisfactory result.
