Direct Under-Sampling Compressive Sensing Method for Underwater Echo Signals and Physical Implementation
Compressive sensing can guarantee the recovery accuracy of suitably constrained signals by using sampling rates much lower than the Nyquist limit. This is a leap from signal sampling to information sampling. The measurement matrix is key to implementation but limited in the acquisition systems. This...
