A low complexity impulse radio based UWB transceiver model for automated arrhythmia analysis

In this paper, a 4 GHz clock synchronized transceiver model is proposed for the transmission of biomedical sensor signals like ECG to perform an automated diagnosis of arrhythmia. The system is based on non-coherent architecture which enables the receiver to be extremely simple and largely insensitive to the transmitted pulse shape. By using energy collection approach, a bank of integrators is used to determine the energy of the signal for specific intervals of time, thus making the receiver efficient in a multipath environment. Detection of arrhythmia requires an accurate estimation of the R-R interval of the ECG signal. The proposed model estimates R-R interval and detects different catastrophic arrhythmias.
