May enhance non-contact vital sign monitoring in noisy settings; leaves open clinical validation before practice adoption.
A novel third-order cyclic cumulant detection method improves the accuracy of non-contact vital sign monitoring using Doppler radar in noisy environments.
Zhao et al. (2017) studied this question. Third-order cyclic cumulant (TOCC) detection method was evaluated on Estimation accuracy for detecting vital signs under low SNR, strong clutter noise and random motion interferences. A novel third-order cyclic cumulant detection method demonstrated better estimation accuracy for detecting heart and respiration rates from Doppler radar signals under low SNR and strong interference.
