In this paper, a method is proposed for chirp rate and initial frequency estimation in the presence of non-Gaussian noise. In this approach, the noise is considered a component of signal phase. After extracting the phase of received signal, we estimate the parameters of interest by using the linear estimators....

As the Internet continues its exponential growth, two of the major problems that today’s Web users are suffering from are the network congestion and Web Server overloading. Web caching and pre-fetching are well known strategies for improving the performance of Internet systems. Web caching techniques...

In the long-term evolution (LTE) system, channel equalization makes compensation to restore the original signal, the paper puts forward iteration sphere decoding algorithm which combines traditional sphere decoding and the improved QR based on the conventional QR decomposition detection algorithm. It...

In this paper we propose a half stacked and full stacked SRAM cell design for low power application. This based on the “Stacking Effect of Transistors” with stacking of the driver and the load transistors to reduce the total power consumed in the SRAM cell. The results obtained on basis of proposed half...

In order to make solar energy competitive with the other forms of renewable energies, a better exploitation of its advantages especially environmental side, this will be possible only with the development of the less expensive and high output efficiency systems. In this paper, the modeling and simulation...

The OFDM technique is predominantly used during the implementation of WiMAX Physical layer. This paper focuses on the PHY-layer design aspects, namely, modulation and coding techniques associated. OFDMA, an extension of OFDM, makes use of Adaptive Modulation and Coding techniques to improve efficiency,...

Wideband application put a new demand on antennas pertaining to size, gain, efficiency, bandwidth and more. This paper presents the design and analysis of fractal antenna which uses the self similarity property of fractal geometry. This unique property is exploited to develop antenna elements that are...

This paper presents the details of avionics system design of a quadrotor. It uses the direction cosine matrix approach to identify the coordinates of the quadrotor and then using PID controller it tries to minimize the drifting error. The aim of the paper is to develop a system which uses a small amount...

Emotions are an essential and productive aspect of human thought or action and human thought is inherently emotional. Emotions are factors which vary as mood varies. When person experience different emotions then there is also change in physiological signals in human body and with this variation comes...

Several traditional encryption schemes have been analysed and based on the literature survey, it has been found that chaotic sequences are very much useful to create randomness. In this paper, a new encryption scheme has been proposed with two phases. In the first phase the input image is transformed...

This paper presents an algorithm for solving the multi-objective reactive power dispatch problem in a power system. Modal analysis of the system is used for static voltage stability assessment. Loss minimization and maximization of voltage stability margin are taken as the objectives. Generator terminal...

In this paper we have proposed a new linear mathematical model for due date assignment on the single machine scheduling problem in a batch delivery system. Some assumptions are used as due dates are controllable, dynamic job arrivals; unforced machine idle and preemption are allowed. In this paper we...

In this paper, an algorithm for segmenting skin regions in color images using color and edge information is presented. Skin colored regions are first detected using a Bayesian model of the human skin color. These regions are further segmented into skin region candidates that satisfy the homogeneity property...

In this Paper I have taken the different buffer (packet) size for different Routing Protocols and study the different performance matrices where we will get the optimize result and where we will get the worst result i.e. where we get the maximum packets and where packet reception at receiver is minimum..In...

In this paper the Koch Fractal shaped Microstrip End Coupled Half-wavelength Bandpass Filter is used to show the effect of space gap on the response with an center frequency of 2.02 Ghz . As the filters are the key elements of telecommunications and radar systems and are important items in the performance...

Delay Tolerant Networks are resource constraint network. Selfish behavior of a node causes it to drop legitimate packets of other nodes, leading to low message delivery and wastage of valuable network resources. Here a Minimax Theory Based Scheme is proposed to distribute credits among non selfish nodes...

Social networking sites are very useful in sharing information, making friends and keeping in touch with old friends. It is an online service, platform, or site that focuses on facilitating the building of social networks and social elation among peoples for sharing interests, activities, backgrounds,...

The secondary service is able to access the spectrum allocated to primary service through spectrum sharing mechanisms. Cognitive radio technology which enables secondary users to share spectrum with primary users in an opportunistic manner can be implemented for this. Scheduling or resource allocation...

Botnets are becoming more hazardous in cyber crime when compared to other malicious activities. Security against botnets is a major concern. Botnet forensics is young science which can answer questions about how, what and where of damage done by bots. The forensic system deals with capturing, recording,...

It is a challenge area in the field of ad hoc networks to support prioritized routing for time sensitive applications, such as multimedia communications, IP telephony and interactive games. However the existing protocols did not consider the special battery discharging behavior of wireless devices. The...

In recent years, The advancement of power electronic technology, novel control strategies and new circuit topologies, the grid connected small wind turbine industry is primarily dominated by the permanent magnet synchronous generators (PMSG) have increasingly drawn interests to wind turbine manufactures....

The design and application of level shifter circuit which is based on single power supply is presented in this paper different from conventional level shifter circuitry. A level shifter may be used to shift any voltage level to a desired level without any leakage current. To reduce the supply routing...

Abstract Induction motors are the most widely used among the all available drives. Particularly squirrel cage motor are rugged, cheaper , lighter , smaller, more efficient requiring lower maintenance and can operate in explosive environment. Under normal operating condition machines are used with three...
