In the current scenario, second opinion of physicians has gained a significant attention in terms of saving life and cost. This requires transmission of Electronic Patient Record (EPR), which is generally carried on a secured network. Despite all safety measures, the primary concern is privacy, security and confidentiality of patient information. Therefore, this paper proposes an invisible watermarking...
Photoplethysmograph is an optical procedure used to determine the physiological parameters identified with cardiovascular system. This paper focuses on the design of PPG acquisition system with reflectance type of sensor circuit to extract the features such as systolic peak, diastolic peak and dicrotic notch. The designed system is tested on 50 subjects of different age groups and the amplitude of...
Cross Talk (NEXT, FEXT), and Inter symbol interference (ISI) degrade the performance of wire line communication system. Equalizer plays a big role in the performance improvement. Zero Forcing (ZF) and Least Mean Square (LMS) algorithm for TDE (time domain equalizer) and FDE (frequency domain equalizer) has been used for minimization of cross talk and ISI. In this paper simulation of ADSL (Asynchronous...
