Double Weight (DW) code families are constructed with different algorithms and fixed value of users at basic code matrix. A single code construction algorithm is proposed for DW code families in which, number of users for basic code matrix depends on the code weight and on a constant value. Mapping is used to provide the greater number of users. Affect of basic matrix (used in mapping) on Bit Error...
This paper presents a preemptive job scheduler based on a 3-layer Backpropagation Neural Network (BPNN) and a greedy task alignment procedure. The BPNN estimates priority values of jobs based on the attributes of their subtasks and the given job selection criteria of the scheduler. The scheduler is formulated in such a way that, at each time interval, the most priority job will be selected from the...
In this paper Compaq patch antenna is designed using array of E shape element and its performance is optimized using defected ground structure. Two array designs are proposed of 1 by 2 elements and 2 by 2 elements and its performances are analyzed. Circular DGS is introduced to enhance the performance characteristics like gain, bandwidth, mutual coupling and better isolation between elements of antenna...
Presently, the utilization of novel digital VLSI circuits increasing exponentially. Recent trends in the design of such circuits are to decrease the node capacitance and power supply requirements. Because of this fact, huge susceptibility to transient faults increases in the nano-range digital CMOS designs. We have constructed a new robust fault resistant D-latch for low power applications. We designed...
This paper addresses the statistical analysis of Transceiver Phase Noise (PHN) effect on Orthogonal Frequency Division Multiple Access (OFDMA) Uplink system performance for arbitrary subcarrier mapping. In most of the previous publications Complex Gaussian distribution of Inter Carrier Interference (ICI) was assumed, however in this paper we derive a closed form expression for the signal-to-interference+...
The article proposes the design of the framework for vehicular ad hoc networks (VANET) for delivery of the authentication keys with minimum delay amongst vehicles having high mobility using fog and cloud computing. We propose to introduce fog computing to extend cloud computing by introducing an intermediate fog layer between mobile devices and cloud thus producing a number of advantages. Since the...
In present work, secure communication scheme for digital images based on discrete time unknown input observer (UIO) design blended with discrete time chaotic encryption is presented. Chaotic signals are pseudo random signals with no periodicity over infinite length. However, the series can be generated with the precise knowledge of the few parameters like system parameters and initial conditions of...
Brain Computer Interface is a reliable communication interface between human brain and external world. It translates human brain electrical activity to useful command by extracting meaningful features from Electroencephalogram signals. In present work, feature extraction techniques and classification methods are proposed for implementation of Brain Computer Interface system. Proposed methodology is...
Cloud computing is most recent advanced rising innovation that provides every kind of service to its users. It is generally based on “pay per usage” methodology that provides an immense Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS) model that altogether form a cloud. However it also has some issues that is to be resolved. Among many issues, Load...
this project entitled “Driver Soberness System for road vehicles” is a safety system. The basic idea behind this system is to prevent and person under influence of alcohol to start and drive any road vehicle. The system takes power form the vehicles existing battery and is switched on as the key of the vehicle is set to ON position. The system then waits for a sample of breath as an input and then...
With satellite power level increasing, the requirement to measure higher Direct Current (DC) has become critical. This paper gives details of two Magnetic Current Sensor (MCS) approaches for high DC measurements. These current sensors are based on saturating core concept to avoid loss of information at high currents due to magnetic fold-back which occurs in conventional techniques [2]. The two approaches...
