摘要
从软件无线电的实现出发对带通欠采样定理进行了完整的推导、分析,得出其等效表达式为2fHn-1,2≤n≤N,并给出了带通欠采样定理在不同条件下的MATLAB仿真结果。最后n≤fs≤2fL结合全数字中频直扩接收机的研制,进一步验证了欠采样定理的实用性。
The bandpass undersampling principle was analyzed based on the implementation of software radio, and the results were shown, which was simulated by MATLAB under different conditions. An application is also given. In the last part of the paper, an application is also given in the digital intermediate-frequency DS(Direct Spread) receiver, and the practicability of the bandpass undersampling principle is further proven.
