摘要
为实现频谱监测、通信侦察等任务,提出了一种基于软件无线电的数字侦察接收机的软、硬件体系结构。该接收机基于高速数字信号处理器、大规模现场可编程门阵列、高速AD芯片、高精度大动态范围AGC电路,实现了信号的宽频段、宽带接收;采用盲信号处理技术,实现了对未知信号的参数辨识、分类、盲解调。
To achieve spectrum and signal monitoring, this paper put forward the hardware and software designing of a software radio receiver. This receiver based on DSPs,FPGA,high speed AD converter and high precision AGC, achieved broad receiving and processing bind. By introducing blind signal processing technology, this receiver achieved the identifying and demodulating of unknown signal.
