According to the conventional Shannon s sampling theorem,in order to represent the
analog signal,the sampling rate should not be less than twice the Nyquist sampling rate.Howev-
er,this theorem only makes use of the bandwidth information.As a result,the collected data
contain many redundant information.The recently proposed sampling method,compressed sens-
ing or compressive sampling(CS),can collect compressed data at the sampling rate much lower
than that needed in Shannon s sampling theorem by exploring the compressibility of the signal.
This paper presents a review on the basic theory of CS.Some of the restrictions and recovery
methods in CS are also discussed.Finally,some potential applications based on CS are presented.
