基于窄带信号抽样的信号高效传输
Signal efficient transmission based on narrowband signal sampling
摘要
Abstract
The Nyquist sampling theorem is one of the important theorems for digital processing of analog signals with finite frequency width,but has some new problems while sampling the narrowband signal in the finite bandwidth ones. On the basis of the reason that the available narrowband signal exists the problems,the narrowband signal is sampled by taking the non-aliasing frequency spectrum of the sampling signal as the foundation,and compared with the signal after sampling according to the Ny-quist theorem. The signal in channel transmission is analyzed by means of related knowledge of communication priciple to get the advantages of the narrowband signal processed with sampling theorem.关键词
