In this study, we are presenting WWT (Walsh Wavelet Transform) technique to compress an image. In recent times, DWT (Discrete Wavelet Transform) & WT (Walsh Transform) are developed as a prevalent methods for compressing an image. In this, WT (Wavelet Transform) is one such significant transform of image compression. Outcome of this is altered with the wavelet type changes. In this paper, we used...
There is an ever-increasing demand on mobile wireless operators to provide voice and high-speed data services and to support more users per base station to reduce overall network costs and make the services affordable to subscribers. Smart antenna technology offers a significantly improved solution to reduce interference levels and improve the system capacity. These systems of antennas include different...
In this paper, two different structures (six elements and fifteen elements) of linear array antenna are designed considering mutual coupling among all the elements. Popular Particle Swarm Optimization (PSO) method is used to optimize the Directivity (D) and Half Power Beam Width (HPBW) by varying the input design parameters, length of the elements and spacing between them. Simulation is performed...
Ever since the rise of technology and communication, the want of security system has also gone up. The indispensable facets of secure data transmission are none other than sheltered, hasty last but not least multifarious cryptosystem. The other dimension of information hiding is steganography. The downside of cryptography is though the secret is cloaked, communication is not rather disguised. For...
H.264, which is the most advanced video compression standard till date, includes novel algorithms for quantization and inverse quantization processes. In this paper, a new hardware architecture exclusively based on combinational logic is proposed for the quantizer and inverse quantizer blocks for real-time video processing. Implemented in Xilinx14.1, Virtex-5 technology, the proposed architectures...
The objective of this paper is to track the maximum power from Photovoltaic panel by varying the converter duty cycle with the help of fuzzy logic based maximum power point tracker. The input parameters of fuzzy logic controller are error (E) and change in error (ΔE). The fuzzy logic controller will generate the converter duty cycle for the inputs given to it from the Photovoltaic panel under various...
