Abstract: The design and implementation of portable TT & C station for ChuangXin No.1 communication microsatellite based on SDR (software defined radio) are described. By the reconfiguration of the programmable devices, the portable TT & C station can receive the narrow band data for telemeter and the spread spectrum data for communication. It can also transmit three data stream(telecontrol, telemeter, communication).

Key words: efficient digital filter, reconfiguration, SDR, digitalization of IF, multirate signal processing
