A QRS Complex detector has been designed for the wearable Electrocardiogram (ECG) systems using Multi Scaled product with booth multiplier and soft threshold algorithm. The raw ECG signal is first digitalized by passing it through an analog to digital converter (ADC), then a Wavelet decomposer is used for the decomposition of the signal into four Wavelet Filter Banks. A Noise detector is connected...
In this paper analytical modeling of Lorentz-force transduced micromechanical resonator is presented at the transfer function level. Such resonators are useful for low-frequency filtering applications in the field of biomedical and RF communication area. The present work focuses on the utilization of Lorentz force actuation with piezoresistive sensing for the realization of vertical flexural mode...
Image compression is the technique of reducing the number of bits required to represent a digital image, which can be accomplished by reducing the redundant and visually irrelevant information present in the images. In this study, a Wavelet Difference Reduction (WDR) coding based image compression technique is proposed which uses Principal Component Analysis (PCA). These techniques are combined in...
In this paper a new realization of electronically tunable current-mode Active-C biquad filter is presented. In the proposed current-mode biquad filter, only a single modified current conveyor transconductance amplifier (MCCTA) as active building block and two grounded capacitors as passive elements are used. The proposed filter can realize three filtering functions namely, low pass (LP), band pass...
Floating point multiplication is a crucial operation in high power computing applications such as image processing, signal processing etc. And also multiplication is the most time and power consuming operation. This paper proposes an efficient method for IEEE 754 floating point multiplication which gives a better implementation in terms of delay and power. A combination of Karatsuba algorithm and...
Data-rates for serial links like PCIe3.0, 10GKR Ethernet, and SATA, go up to several Giga-bits/second. As the transmission data rates increase, the signal strength at the receiver side decreases due to channel loss, Inter-Symbol-Interference (ISI), crosstalk, and reflections. The Input-Output (IO) buffers are, therefore, designed with inbuilt equalization circuits to recover clock and data at the...
Remote sensing provides the facility of acquisition of data associated with Earth's surface to observe regular changes. An important characteristic of imaging sensor is resolution which is classified in four different ways: (a) spatial; (b) spectral; (c) radiometric; and (d) temporal. During recent decades, the emergence of multispectral sensors provides the data with enlarged quantity of spectral...
This paper describes a new technique to simulate MATLAB system models in PSpice environment. The algorithmic component of the design is developed using MATLAB, and then exported to a C-model which can be read and simulated by PSpice using its newly developed PSpice Device Modeling Interface (DMI). The paper describes in detail the changes required to make the MATLAB C-Model compatible with PSpice...
Smart grid is capable to produce, distribute, and consume power in the most efficient way. This will allow more power at home and industries at low cost. To achieve above the best communication infrastructure is required to deliver reliable and economical services throughout the grid system. Smart grid can also accommodate power generation from local solar power and power generated through wind turbines...
We analyze and study the performance of Amplify and Forward cooperative diversity wireless communication network with best-relay selection over Weibull fading channel. In this paper, a closed-form expression for the moment generating function (MGF) of the total signal-to-noise ratio (SNR) at the destination is derived in terms of the tabulated Meijer's G-function. By the help of this derived MGF expression,...
This paper demonstrates the Data aided (DA) synchronization for single user in IEEE 802.15.4a channel for coherent and Non-coherent UWB-IR receivers. Random Timing Offset before every transmitted sequence is estimated using Walsh codes which act as pilot sequence to achieve timing synchronization. Sliding correlation window of appropriate length is used to perform correlation of received bit stream...
The designing of rectangular microstrip patch antenna requires classical formulae to calculate. For every new design same formulae are used which is time consuming and lengthy. The Bhatnagar's Postulate gives the idea of transforming one design into another by using normalized thickness H (ratio of height of substrate to guided wavelength) and scaling factor ψ (ratio of the square root of the dielectric...
