摘　　要：针对手机信号检测及追踪定位技术在主动性、灵活性和精确度等方面存在的难点及不足,设计了一种基于TD-SCDMA基带数字信号处理的手机终端探测技术。为了提高探测设备的实时处理能力,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,优化并实现探测算法。经现场测试,该设备能够快速、准确地对选定的TD用户终端进行探测、跟踪和定位,验证了DSP设计的实时性和可靠性。The technology of mobile phone detection and location is lack in inactivity,flexibility and accuracy.Aiming at this situation,the paper introduces a technology of mobile phone terminal detection. It is based on baseband digital signal processing techniques of TD-SCDMA.In order to improve the ability of real-time processing,a DSP chip with hign performance,TMS320C6416, is selected as the core of processing.And the hardware system is designed with other devices.Then,the algorithm is optimized and realized.At last,the test result indicates that the system works quickly and accurately.Thus,the design of DSP satisfies the require- ment of real-time performance and reliability.
