Analysis of Signals Affecting the Quality of Power

Abstract

Electricity is the most revolutionary development in the human history. Efficient transmission of electric power is of at most importance in the current scenario.power Quality is an important concern for utility as well as consumers. Power quality is one of the major concerns and emerging issues in the present era. “Power quality is a set of electrical boundaries that allows a piece of equipment to function in its intended manner without significant loss of performance or life expectancy”. With increasing quantities of non-linear loads being added to electrical systems, it has become necessary to investigate the power quality issues as all electrical devices are prone to failure when exposed to one or more power quality problems. The Hilbert transform is an important operator in signal processing, e.g., the definition of the “analytical signal” uses the Hilbert transform. All kinds of transient power quality events occur frequently, causing power equipment damage and even lead to large scale blackout. Hilbert Huang transform is better than traditional transform approaches. Features are extracted from the power electrical signals by using Hilbert Huang Transform (HHT). Hilbert-Huang transform, is developed by the need to analyze the non-linear and non-stationary data.It is expected to detect the characteristic features from the PQ disturbance signals, which are obtained using Multivariate Empirical Mode Decomposition [MEMD] method

Ber Performance of Wireless Communication System using Jscc and Mio Encryption

Journal of signal processing and wireless technologies, Available online 9th August 2017

Abstract

These Most of the communication today occurs through the wireless medium. In such a communication, due to the openness of the network, the transmitted signal may get added with the additive noise present in the channel, which may severely degrade the performance of the communication system. Also, since the transmission of highly confidential messages takes place through wireless networks, security and integrity of the transmitted signal is a challenging issue in such networks. Physical layer security techniques are mainly based on channel characteristics. It has been proved that, using a proper channel coding, can achieve information-theoretic secrecy thereby making the eavesdropper hard to break the encryption, even it has unlimited computing power. This paper combines analog joint source-channel coding (JSCC) followed by multiple inter-symbol obfuscation (MIO) encryption to enhance the security and reduce the bit error rate of wireless communication system. The BER of the proposed method is compared with MIO scheme and the proposed method exhibits a better BER performance than the MIO scheme

EMOLGA The Air Mouse

Journal of signal processing and wireless technologies, Available online 20th July 2017

Kiran Borade | Ishita Dixit,Shital Bauskar

Abstract

This paper reviews the technology for using hand gestures as a means for interacting with computer. That is to develop an Air Mouse which operates on hand gestures. Air Mouse is convenient and health friendly device that is capable of replacing the existing optical mouse. It is a wearable mouse that is implanted on a glove which can be worn by the user. It consist accelerometer to sense the hand movements, hall effect sensor for the click operation and scrolling, Arduino board which has microcontroller and ADC implemented on it. It is a wireless device hence to communicate with host device it uses Wi-Fi. The programming of Arduino chip is done using Arduino Software Integrated Development Environment (IDE). The main goal of Air Mouse is to achieve better quality Human Computer Interaction (HCI

Abstract

This image fusion is that to employ explicit luminance and contrast masking models. By the Dual Tree Complex Wavelet Transform of each input image. The coefficients are retained and the retained information would be in most effective way.For this image fusion Discrete Wavelet Transform is used.

Power Allocation Strategies for Wireless Relay Networks with Analog Network Coding: Survey

Journal of signal processing and wireless technologies, Available online 20th July 2017

Basanti. Ghanti | Siddarama R Patil

Abstract

Relay aided communication with network coding can bring spectacular performance enhancements for wireless networks. The proper design of power allocated to each of the nodes involved in the communication is essential as it has impact on the performance when Analog Network coding (ANC) is used. This paper presents a survey on recent power allocation strategies, intended objectives, practical constraints that have been considered, and corresponding performances for networks with ANC protocol.
