Compression, encryption, encoding and modulation at the transmitter side and reverse process at the receiver side are the major processes in any wireless communication system. All these steps were carried out separately before. But, in 1978 R. J. McEliece had proposed the concept of combining security and channel encoding techniques together. Many schemes are proposed by different researchers for...
Electrolytic capacitors are the essential electronic component of the power converters. Few methods are implemented for fault diagnosis or prognosis of the electrolytic capacitors. Most of these methods are based on the parameter like equivalent series resistance (ESR), capacitance (C), operating temperature (Tc), DC operating voltage (Vo), output ripple voltage (Vr) or ripple current (Ir). This paper...
Video content management system is now a day's becoming a very popular and widely used system in multimedia retrieval. With the increase in bandwidth and internet availability lot of multimedia digital content such as movies, videos, TV shows and sports highlights are easily available. This facilitates the easy access of digital content to users. In such situation when users don't have enough time...
The multiple input multiple output (MIMO) antenna transmission system has proved to be highly spectrally efficient. It has also been shown that the capacity of a MIMO channel increases linearly with the number of antennas. Space Time Block Coded (STBC) systems can obtain high diversity order maintaining the high data throughput with a reduced complexity in transceiver configuration. 2 × 2 (Alamouti...
CORDIC (CO-ordinate Rotation Digital Computer) algorithm is the most important solution for realizing the different digital modulation schemes. Modulation is the method of varying the carrier signal according to the amplitude of the modulating signal. The CORDIC algorithm is used in the rotation mode. This mode is used for converting polar coordinates to rectangular. This paper shows that how to use...
RFID is well known technology with widespread applications in diverse fields by now, supply chain management and retailing industries are in forefront of RFID adoption on large scale. RFID tags attached to objects in supermarkets offer many advantages over the existing barcode technology including one trace speedy billing process and in overall automated store management. Though RFID adoption in supermarkets...
Wireless devices and connectivity are becoming more vital on everyday life. Key to the wireless revolution is the implementation of multi functionality, broadband reception at high data rate and miniaturization of wireless devices and its accessories. High performance small antennas such as micro strip antennas are emerged as a key driver in marketing and next generation devices. This paper begins...
Signature recognition is one of the most significant research fields in the area of identity recognition based on biometrics. To create a highly Scalable, Pluggable and Faster online signature recognition system, the authors Dr. Vinayak Bharadi and Mr. Godson D'silva had proposed an architecture for implementing online signature recognition system on a public cloud [1]. This proposed architecture...
In recent era, massive computing is inevitable and mostly required for graphic processing of high resolution. Massive computing in high resolution is mainly dominated by GPUs. This paper focuses on start of GPU since era of 1980's and its evolution till date. The possibility of designing own GPU with the help of reconfigurable computing on FPGA is also discussed. This paper is exploring the scenarios...
The FIR filter used in DSP has been focus in new product design and technical literature for decade of years. The electronic communication fields which adopt DSP include multimedia system, communication system, image processing, RADAR, medical etc. Now a day, digital signal processor becomes the heart of digital camera, cell phone, hearing devices, aid devices, audio and video players, satellite and...
There are various algorithms used for assigning tasks to heterogeneous processors. We propose an algorithm to assign N tasks to K processors. The motivation of this algorithm is to address the drawback of Minmin+, Maxmin+, Sufferage+ in solving problems with highly skewed costly distributions. The proposed algorithm is easy to implement and we have illustrated with detailed pseudo codes.
In nature, the texture is an omnipresent visual experience. The dynamic texture contains chromatic, spatial and temporal correlationships. Dynamic textures are categorized into linear dynamic texture and Nonlinear dynamic texture. Several methods have been employed to model dynamic textures like Singular value decomposition (SVD), Higher Order Singular value decomposition (HOSVD), and novel method...
The main idea behind cloud system is to provide the unlimited resources. Existing DawningCloud is an efficient cloud system for scientific communities. It reduced the total resource consumption of cloud resource provider and cloud users. However, DawningCloud simply used First Come First Served (FCFS) scheduling Policy and did not investigate the effect of different scheduling techniques on them....
Database design process involves analysis of system requirements described in natural language for manual extraction of conceptual schema. This is a tedious process and prone to human error. Earlier approaches of automation of this process had made use of either a finite set of rules, Context Free Grammars (CFG) or semantic understanding. Rule and CFG based approaches are not robust enough to cover...
The cardiovascular disease is having major impact on human life, in order to diagnose the cardiovascular disease ECG retention along with its information has a got prime importance. Mostly ECG reading has got concern of retrieving correct information by reading the ECG at first glance, which is tackled by having an ECG with all desirable information in it. Normally ECG is associated with variety of...
In this paper, we have developed algorithm which combine features from an object image to recognize it. Object recognition is the most interesting and challenging area of research due to its importance to a wide range of applications as objects differ in shape, size and color. The descriptors used for feature extraction in the existing methods for object recognition are mostly intensity based. For...
The aim of the system is to implement the new canny algorithm for parallel preprocessing block with no loss in edge detection results compared with the original frame-level Canny algorithm. The methodology employed here is distributed canny edge detection algorithm on the basis of threshold segmentation as the segmentation has good advantage in noise restraining with wide applicability and computes...
The paper presents a novel approach to identify the singers using harmonic spectral envelope constructed from pitch of singing voice. This new representation of singing voice demonstrates that harmonic spectral envelope exhibits certain acoustic qualities that can characterize the identity of the singer. Two different approaches are implemented to extract the pitch of singing voice; Cepstrum technique...
The filling-in of missing region in an image is known as Image Inpainting. Inpainting is the process of modifying an image or video in a form that is not easily detectable by an ordinary observer. Recently, the image Inpainting technology is a hotspot in computer graphics, its having important value in a edge preservation, to add special effects, removing unnecessary objects etc. In the fine art museums,...
