FIR Filter always remains in linear phase with the help of symmetric coefficient. This feature makes it ideal for phase-sensitive applications like data communications. Design of FIR filter with energy efficiency makes excellent sense to achieve energy efficiency in digital selected frequency module of communication. We are using scaling of output load from 5000 to 0 pF to show an effect of output...
The paper presents a naturalness preserving transform (NPT) based collusion and compression resistant watermarking technique for video. An image that is statistically similar to a video frame is chosen as the watermark and this image is embedded independently in consecutive frames of the video. To enhance the resistance to inter frame collusion based attacks, a non-overlapping block matching is used...
Cognitive radio is the key technology for future wireless communication. Spectrum sensing is one of the most important functions in cognitive radio (CR) applications. It involves the detection of primary user (PU) transmissions on a preassigned frequency band. PU licensed band can be sensed via appropriate spectrum sensing techniques. In this paper, we propose an energy detector utilizing adaptive...
Abstract-In this work, we study the application of Perron-Frobenius theorem for computing trust in the VANET environment. Safety critical and safety related messages in a VANET can lead to major changes in the behavior of vehicles moving on the road which can prevent unpleasant traffic situations. False messages can result in serious conditions like collisions. Trust management in VANETs is necessary...
In this paper a design technique for a Stepped impedance Micro strip Low-pass filters is presented by using the artificial neural network (ANN) modeling method. Required dimensions of the micro strip filter layout are used to get the input-output relationships in the ANN model. This paper presents the design and analysis of Stepped impedance Micro strip Low-pass filters at cut-off frequency 1.8 GHz...
Quantum-dot cellular automata (QCA) is an approach to computing which eliminates the need for transistors or current switches by representing binary digits as charge configurations rather than current levels. Coulomb interactions provide device coupling without current flow. The QCA clock signal consists of an electric field being raised and lowered. By introducing clocked control of the QCA cell,...
VHDL environment for floating point arithmetic and logic unit design using pipelining is introduced; the novelty in the ALU design with pipelining provides a high performance ALU to execute multiple instructions simultaneously. In top-down design approach, four arithmetic modules, addition, subtraction, multiplication and division are combined to form a floating point ALU unit. Each module is divided...
A simple model has been planned for human presence sensing in a closed room using a scanning type pyrometric detector, embedded system and intelligent software. Sensors are to be mounted on a rotating platform for scanning of the field of view at regular intervals and at slow speed. This concept is intended to monitor movements of human at desired location and activate equipment accordingly.
