摘要
在广义采样定理的信号模型的基础上,讨论了非均匀采样时带通信号的重建问题,导出了重建函数的傅里叶像的一种有效计算方法,最后给出了带通信号重建的计算机仿真实例。
Based on the signal model of generalized sampling theorem, the reconstruction of a bandpass signal from non-uniform samples is discussed. An efficient way of computing method of the Fourier images of reconstructing functions is derived. Finally, the simulation example is presented to illustrate the reconstruction of bandpass signal.
