摘要 研究多频带信号的直接射频采样技术,根据镜像频率和采样频率的对应关系,推导出一种多频带信号的采样频率搜索算法,并结合软件实现中的计算截尾误差问题给出一种编程可实现的算法流程.仿真结果表明,该算法能够有效地找到最小合理采样频率,适合工程实现. To investigate the direct radio frequency（RF） sampling techniques for multiple band signals, a new method of finding the minimum sampling frequency for multi-band signals is proposed. Based on the principle of bandpass sampling, a searching algorithm can be derived using the corresponding relationship between image frequency and sampling frequency. To correct the calculation errors due to truncation of float-point number, the algorithm constraints are amended and the implemental flow chart is built. Simulation results show that the proposed method is efficient with relatively low cost and it is convenient to be applied in engineering.
