摘要
Demodulator is a vital part for deep space telemetry system. On the condition of low signal-to-noise ratio, lower bit rate and more sorts of modulation types are used in deep space communication. Comparing with the conventional telemetry demodulator, some improved technologies are added to satisfy the requirements of deep space telemetry. An overview of the demodulation technology is provided here and key technologies applied in deep space demodulation are analyzed. The testing results of demodulator show that the demodulation loss can be lower than 0.3dB, bit synchronization and the Es/N0 estimation can be achieved correctly at less than -5dB.
