RF biomedical signals transmission system for telemedicine applications

In this research work, a radio frequency (RF) system under QPSK modulation is developed for the transmission of biomedical signals such as EMG and ECG in the 2 GHz band. The system is implemented through a transceiver that operates in 4G applications through a dual transceiver. The signals are acqui...

Sumario:In this research work, a radio frequency (RF) system under QPSK modulation is developed for the transmission of biomedical signals such as EMG and ECG in the 2 GHz band. The system is implemented through a transceiver that operates in 4G applications through a dual transceiver. The signals are acquired by means of the ECG/EKG acquisition card and surface electrodes, the management and treatment of the signal are carried out in C language, and a quadratic bandpass filter is implemented in the digital modulation on the ARRADIO+SocKit card. The implementation developed is a contribution to Telemedicine work for the post-pandemic era. The system makes a spectral evaluation of the quality of the QAM constellation, as well as the spectral analysis of the invasion of adjacent bands. As future work, it is intended to migrate to 5G in a transceiver that operates in the 3-6 GHz bands.
