    Oversampling Technique for Peak to Average Power Ratio Measurement of Discrete Time OFDM Signal

    When measured, the Peak to Average Power Ratio (PAPR) of the discrete Orthogonal Frequency Division Multiplexing (OFDM) signal comes out to be less as compared to its continuous counterpart. This happens due to non-consideration of some of the peaks while measuring PAPR of the discrete time OFDM signal. This paper...

    Hardware Implementation of Face Detection Using ADABOOST Algorithm

    One of the main challenges of computer vision is efficiently detecting and classifying objects in an image or video sequence. Several machine learning approaches have been applied to this problem, demonstrating significant improvements in detection accuracy and speed. However, most approaches have limited object detection to a single class of...

    Low Power CMOS 1-Bit Full Adder Cell Based on Voltage Scaling

    Operating an Integrated circuit at the prescribed Voltage scaling (constant field scaling) is preferable for reliable circuit operation under temperature fluctuations. In this paper, the authors proposed to design 1 - bit full adder by "Changing the threshold voltage and W/L ratio" under temperature variation insensitive conditions. They measured power...

    Secure Localization Technique for Wireless Sensor Networks

    A Wireless Sensor Network (WSN) consist of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibrations, pressure, motion, pollutants and etc to cooperatively pass their data through the network to a main location. The more modern networks are bi-directional and control the activity of...
