摘　　要：针对移动终端用户身份识别的技术需求,设计了一种基于GSM和CDMA双模制式下基带信号处理的主动探测系统。为了满足主动探测系统的实时处理需求,采用高性能的DSP芯片TMS320C6416作为核心处理器,结合其他器件设计硬件系统,完成基带信号处理板中DSP芯片硬件接口的设计。经现场测试结果验证,系统能够实现对开机状态下GSM和CDMA移动用户身份信息的快速捕获,进而表明本设计可满足系统实时性和可靠性的要求。According to the terminal user identity recognition demands, an active detection system is designed based on base- band signal processing in GSM and CDMA network. To satisfy the real-time processing demands, the high performance DSP chip TMS320C6416 is used as the core processor,and some other devices are used to design hardware system and DSP chip hardware interface on baseband signal processing board. Experimental results show that this system can quickly fetch terminal user identity information in GSM and CDMA network, which can satisfy design demands of detection system in real-time and accuracy ability.
