Embedded ECG Acquisition System Based on Compressed Sensingx

摘要

The traditional electrocardiogram (ECG) acquisition system is generally based on the Nyquist sampling theorem of the MCU acquisition system. The problems caused by this are complex computational processing and storage of data. This paper proposed an embedded ECG acquisition system via compressed sensing. The system uses a 32-bit embedded ARM processor combined with a compressed sensing algorithm to transmit the collected ECG signals to the computer after noise reduction and compression processing. Then reconstruct the ECG signals with different reconstruction algorithms. The experiment proves that the system has the characteristics of high precision, low power consumption and portable power saving.
