A VLC Enabled Indoor Navigation System for Visually Impaired People Abstract-The WHO committee broadly estimated that about 10% of the world population is disabled. India is now been a home to the world’s largest number of blind people. In an entire world there are 37 million people across the globe who are blind over 15 million are from India. In order to help blind people, […]
Seam Carving Approach for Multirate Processing of Digital Images Abstract: – This paper presents a new approach called Seam Carving for multirate signal processing of digital images. Increasing and decreasing the sizes of digital images are common place in day-to-day image processing. These methods involve long procedures and sometimes consume more time for getting implemented. Whereas, using the Seam Carving method eradicates the excess time […]
Design of an Efficient Frequency Synthesizer used For Multi-Band OFDM Abstract— This journal describes the design of a 3GHz -10 GHz [1] frequency synthesizers for Multi-band OFDM in an Ultrawide band (UWB) transceiver at 180nm CMOS technology. As there is a requirement of high speed data rate, reduction in chip size and low power consumption for wireless devices there is demand for high speed complex […]
Implementation of Efficient Fixed Point ALU with 32 Bit Processing Capability Abstract— Exploiting computational precision can improve performance significantly without losing accuracy in many applications. To enable this, we propose an innovative arithmetic logic unit (ALU) architecture that supports true dynamic precision operations on the fly. The proposed architecture targets fixed-point ALUs. In this paper we focus mainly on the precision controlling mechanism and the […]
Offline Stereo Camera Calibration of Raspberry Pi Compute Module. Abstract- Computer vision has become a very popular field due to its numerous applications. Stereo imaging, one of the areas of computer vision is frequently used in many applications like autonomous robots to calculate the free path, 3D reconstruction of environment, automatic cars, travel aid for visually impaired and many more. The major step in stereo imaging […]
A Review Study on Dual Band Notched Antenna for UWB Applications Abstract: Ultra-wideband applications have grabbed much attention in the field of antenna because of it’s extremely wideband for high data rate applications. Since UWB antennas may transmit baseband signal without a carrier, the RF front end can be simplified and become inexpensive Keywords: UWB, Dual Band Notched Antenna, Multi Band Antenna, Bandwidth Enhancement. INTRODUCTION […]
Simulation and Modeling of Fractional-N sigma delta PLL for Quantisation Noise Optimisation Abstract—Wireless Communication has expanded and achieved great heights. It has increased demand for rate of data transmission using low noise clock. Fractional-N frequency synthesizer is used most commonly in today’s wireless technologies. This paper presents simulation and modeling of fractional-N frequency synthesizer and compares architectures that optimize quantization noise. Fractional-N frequency synthesizer is […]
Abstract: Water is the most important Nature’s gift to the mankind. Without Water there is no life. Now man understood its importance, especially where water is not easily available. Now this is being managed by the proper manner in city areas where the use of water is more than its availability. This is one of the motivations for this research, to deploy computing techniques in […]
