| 摘 要： | 根据多项滤波器组理论和FFT方法提出并实现50%覆盖的均匀信道化宽带数字接收机。这种宽带数字接收机把整个采样频带划分成若干并行信道输出,使得信号全概率截获,是侦收跳频、突发以及自适应通信信号接收机的理想前端。主要应用于软件无线电的实现和电子战中。主要阐述宽带数字接收机信道化原理、软件仿真和硬件实现,并为实际工程需要设计了算法、程序和硬件平台,实现了0~100 MHz频率范围内8信道的数字信道化。

| Abstract: | The uniform channelized wideband digital receiver with 50% coverage is proposed and realized according to the multiterm filter set theory and FFT method.It is mainly applied to the realization of software radio and electronic warfare.The entire sampling band is divided into several parallel channels,which makes the signal intercepted all probability,and is the ideal front-end receiver in investigating the hopping frequency signal and adaptive communication signal.The principle of channelized wideband digita... |
