Compressed sensing (CS) is often applied at the digital level. We consider the case where CS follows a $\Delta \Sigma$ data converter and we show that CS can be practiced directly on the $\Delta \Sigma$ stream. In the proposed scheme, an appropriate sensing matrix incorporates the ability to get rid of the quantization noise from the $\Delta \Sigma$ modulator. We also show that a suitable sparsity basis enables the CS information recovery to be practiced directly at the Nyquist rate and that decimation, which is typically inherent in $\Delta \Sigma$ data acquisition, is not needed. Furthermore, the low depth of $\Delta \Sigma$ streams allows CS measures to be taken without multipliers, streamlining arithmetic blocks. A test case based on electrocardiograms is used to validate the approach. |
