Abstract This paper presents the design of a dual-frequency rectangular microstrip patch receiver antenna for Indian regional navigation satellite system (IRNSS) also called NAVIC. The dual feed single layer antenna works on operating frequencies at L5 band (1176.45 MHz) and at S band (2492.5 MHz). Here feeding is done through two ports. Hence antenna is […]
Abstract IoT (Internet of Things) is the paradigm in which efforts are being made to enable seamless processing of information by integrating physical and digital world devices that can be used ubiquitously. Integration of IoT and cloud computing is the major research area where the data collected from the various high data rate sensors and […]
ABSTRACT This paper presents the functional design and integration of a complete WSN platform that can be used to remote environmental monitoring and target for IoT applications. The system of physical object devices, vehicles, buildings and other items embedded with sensors, electronics, software and network connectivity that enables these objects to collect and exchange data, […]
Abstract In this paper, we design a metamaterial based antenna for wideband applications. For the design we consider a unit cell of MM by integrating a U shape patch section with T shape patch, Three such unit cells were attached together to form the desired wideband antenna. Here the dielectric substrate used is Rogers RT/duroid […]
Abstract The performance of wireless communication system is degraded by the burst errors due to deep fades under multipath environment. So, techniques like forward error correction algorithms or automatic repeat request (ARQ) or a combination of both (hybrid ARQ) eliminates the bit error rate (BER). The paper focuses on the performance comparison analysis of different […]
Abstract In microwave or synthetic aperture radar or radar image formation, a speckle noise is generally added. This noise is available in coherent imaging systems like radar image capturing, medical image capturing, etc. De-speckling methods are used to de-speckle the available speckle noise from these speckled systems. In optical image formation, other noises are added.An […]
Abstract In this paper, the performance of the signal and denoising techniques using different types of Wavelet Transform techniques is evaluated based on the different performance metrics such as Signal to Noise Ratio(SNR). A new Complex Wavelet Transform technique called Hybrid Dual Tree Complex Wavelet Transform, has been proposed in this work, so as to […]
Abstract In Present days we are going with paperless environment for the documentation purpose in order to save the lives of trees. The documents may consists of text, symbols, tables, graphs, logos and signatures and other features also. Out of all these features the signature and logos are having their own unique properties in the […]
Abstract Change detection techniques are playing major role in order to know the changes in different situations. Using these methods, we can know the changes that are occurred or occurring on earth due to climatically changes or degradation of certain areas. Change detection will help us to observe the different areas on earth remotely. The […]
Abstract Classification of images obtained from satellites is a challenge now-a-days in order to know the information contained by them. This requires the adaption of the present state-of-art classifiers. Correct information can be retrieved only with good classification method. But single classifier may not meet the requirement, so that ensemble techniques are preferable. For classification […]
