摘要
为了实现多带模拟信号的有效采样,根据多带模拟信号的特点,建立了一个在平移不变空间上的多通道采样模型;利用插值函数实现信号的完整重构。以多带正弦信号为例,验证了该系统可以实现多带模拟信号的采样与重构。
According to the analog signals＇ feature,a model of multi-channel sampling in shift-invariant space is built up.In order to effectively sample multi-band analog signals,interpolating function is used to achieved reconstruction of signals.Take multi-band sinusoidal signal for example,simulation and experiment demonstrate that the model can effectively realize sampling and reconstruction of multi-band analog signals.
