摘要
采用ADSP-TS201高速数字信号处理器(DSP)进行数字中频通信侦察系统的设计,利用DSP超高性能的处理能力以及由可编程逻辑器件FPGA支持的高速接口数据交换能力,实现了通用的通信侦察信号接收处理平台。利用该系统平台开发了通信侦察中的信号搜索及调制识别功能,并通过试验表明该系统能达到对信号实时处理和快速准确识别的目标。该系统还具有灵活性和可扩展性,满足通信侦察高性能、多任务的需求。
In this paper, ADSP- TS201 Digital Signal Processor （DSP） is adopted to design the digital intermediate frequency communication reconnoitering system. By utilizing the high processing ability of the DSP and the high - speed data exchange ability supported by FPGA, a general signal receiving and processing system is fulfilled for communication reconnoitering. Based on this system, such functions as signal search and modulation recognition have been developed and resulted in flexibility and scalability to meet the need of high and multiple performance in communication reconnoitering system .
