In this paper, we propose a probabilistic combining in amplify and forward relay protocol in Rayleigh faded wireless cooperative communication systems. This probabilistic combining works on minimum bit error rate (MBER) criterion using the closed form expression for the probability density function (pdf) of the signal to noise ratio at the output of the selection combiner in an amplify and forward...
The Data communication over the Transmission line can be done through Smart Grid using Power Line Communication (PLC). The Power Line Communication technology is considered as economic and reliable source of communication technology. It became more convenient and prominent for standalone Renewable Energy Systems (RES) which are remotely located. Smart grid's metering and monitoring process are done...
Steganography is a technique of concealing information which has gained more popularity in digital world. It can be used in different formats although image steganography is commonly required because of its immense presence over internet [1]. Many coding techniques have been deployed to minimize the statistical impact of embedding bits behind the cover. In this paper, we propose a flexible scheme...
In this paper, range-free 3D node localization (in anisotropic environment) method using the application of bio-inspired algorithm, i.e., Firefly Algorithm (FA) is proposed. Nodes are deployed over the three layer boundaries in which the upper layer contains the anchor nodes (known position) that are randomly distributed and the middle layer and the bottom layer contain the randomly distributed target...
In this paper, we have explored a potential spectrum sharing technique based on the power allocation in fading environment under transmit power constraint at secondary user/cognitive user (SU) and the interference power constraint at the primary user (PU). In addition to this, we have also analyzed the outage capacity limits over the fading channel, when the partial channel state information is provided...
Research on increases in efficiency in illumination systems has been mainly focused on the luminaires used. This paper describes how optical fibers can be placed in a room to collect unused light and then transmit it to an area needing the illumination. By this method an efficiency can be realized by a reduction in the number or power consumption of luminaires. The light that is emitted from the fiber...
Presented here is a design of a UWB antenna with four notches. The notches are achieved using overlapped CSSRRs and ground resonators. The four notches are at frequencies 3.6GHz, 4.6GHZ, 5.0GHz and 5.8GHz, where these four frequencies fall in WiMAX, HiperLAN, HiperLAN and WiMAX bands respectively. The notches in the response are created by resonating elements placed at these four frequencies to avoid...
Linear patch arrays can be very useful where space is the matter of concern in one direction. Like planar array, linear arrays are also capable of providing high gain and directivity with beam scanning. The paper focuses on air borne applications. Proposed linear array are suitable due to its conformability and meeting the constraint of space for such applications. The design presented in this paper...
Battery powered wireless sensor networks (WSN) although can be installed at reduced cost but due to their high powerconsumption and corresponding need for regular battery replacement has made wireless sensor network difficult andcostly to maintain. Energy harvesting is the process by which energy readily available from the environment, and iscaptured and converted into usable electrical energy. Combining...
The authors proposed an evolutionary algorithm based on quantum particle swarm optimization to generate flattop beam from a linear array of isotropic antennas. An effort is also made to reduce the side lobe level including multiple null placements with minimum variation in ripple of flat-top beam. This is generally done by changing excitation current amplitude of the elements. Phases of some of the...
Detection of cancer involves estimation of elasticity by measuring density and velocity. The velocity of the induced transient waves orthogonal to the ultrasound wave motion is used to calculate the stiffness of tissues in differentiating between malignant lesion and benign lesion using transient elastogram. For computing the velocity of transient wave propagation an ultrafast scanner is required...
In this paper, the importance of measuring dielectric properties of solid materials is discussed, which is of great significance in the fields of biological and agriculture science. The analysis and simulation of the solid materials is done by employing a hollow cylindrical cavity resonator. This method provides parameters of high accuracy for calculating the permittivity and permeability of solid...
In this paper a blind estimation method based on second order statistics is described for the estimation of channel impulse response of indoor optical wireless communication system. Unlike the other training sequence based estimation methods this method does not require a training sequence to be transmitted with the transmission data to estimate instantaneous channel impulse response. The elimination...
In this paper, a compact 3D U-shaped Yagi-Uda nantenna with different high permittivity and permeability materials has been studied and compared with variation in the spacing between the elements. Modern communication demands high speed data processing at nanometer wavelength and it is basically relying on the speed and bandwidth of emitters & detectors on the nanoscale. In order to achieve this...
In multiple-input multiple-output (MIMO) systems, symbol error rate (SER) performance of Gamma shadowed Weibull multipath fading channel has not been investigated in existing literature. In this paper, MIMO system is realized with maximal ratio combining (MRC) technique that operates over Weibull-Gamma (WG) fading channel where WG forms a generic distribution. Higher order modulation like 16-phase...
