The research proposes to examine communication channel, error in the communication channel, channel coding, convolution codes, code concatenation, turbo codes, decoding algorithms for turbo decoding such as SOVA, log-MAP and interleavers for turbo codes.

Design and Development of an Efficient Advanced Parallel ADC for High Computing Applications

This technique reduces the execution time up to 50% which in turn reduces the power dissipation for computation. For the proposed design, the work is planned to carry by developing a software reference model using MATLAB (Simulink or Code), compare the performance of the proposed design with conventional ADCs then develop a parallel ADC model using HDL programming (VERILOG/VHDL), synthesize the design and generate reports on power and time for comparison and analysis.

Nature Inspired Computation Based Floor Planning in VLSI

NIS can be used to adapt solutions to changing circumstances as VLSI floor planning is an important aspect in chip design. It involves the arrangement of a set of rectangular circuit modules on a chip to minimize total area and total interconnecting wire length without overlap between the two modules as production cost increases due to larger chip sizes, while there is an increase in power consumption due to longer wire lengths and thus, both will decrease system performance.

Measurement of Total Electronic Content (TEC) in the Ionosphere Using Dual Frequency GPS Receivers

Orbit Characterization of Space-Borne Synthetic Aperture Radar Performance Using Ground Deployed Corner Reflectors

Ultrasound Image Retrieval by Hierarchical Decomposing for Medical Image Application

This research focuses on the CBIR applications in the medical domain, discussion of challenges and opportunities in the medical domain, and speculations for future research. The research involves developing different methods for content based image retrieval.

Improved Content Based Medical Image Retrieval Using FCM & Multiple Texture Features

The objectives involve developing novel methods for image retrieval system based on FCM (fuzzy c-means clustering) using multiple texture features (hu moments and Gabor texture features) and multiple distance vectors.

Modeling and Simulation of Human Cardiovascular System Using Neuro-Fuzzy-Genetic Engine

The primary focus of this research is to develop a cardiovascular model for normal operations by using electronics circuit having different components.

Automatic Recognition and Analysis of Statistical Process Control Patterns Using Neural Network

Artificial Neural Networks (ANN) for SPC chart pattern recognition’s usage have motivated researchers to go ahead with it. The neural network technology and its application have overcome the few drawbacks in the traditional expert system approaches.

Embedded System Design

top engineering colleges

Department is actively involved in designing of unmanned vehicles for land, water and air.

Problem statement : To build an efficient Autonomous Land vehicle which takes into account certain factors, detects collision and changes its direction to reach the given destination with the help of the waypoints.

Methodology : Understanding the design and working of a Remote controlled land vehicle (Robot). Design and development of an unmanned land vehicle model. Initially the design of control system of vehicle is done i.e., wheels are controlled through the Raspberry pi 3 with L298 driver. Then the development of obstacle detection and avoidance system is carried out using 3 ultrasonic sensors (Front, left and Right side obstacles). Image processing is done with the help of Kernel and Contour Algorithms using Raspberry pi through openCV for Traffic color and sign detection. With the help of GPS co-ordinates way points and algorithm, the navigation of vehicle from source to destination has been achieved.

Outcome : the course is assumed to be smooth, the GPS module would constantly provide accurate information and that the power supply would be constant. This is an ideal case. During testing however these factors come into play and cause variations in the results. The rover completed the course but overshot one or two vertices on occasion. The speed and direction was hindered by the uneven surface which caused the rover to veer off the path towards the end. After much initial tests prior to the demonstration, the battery output voltage was lower than its initial value and the vehicle had to be connected directly to a PC in order to provide enough current for all the components. The vehicle did manage to complete the entire path at a relatively fast pace with all the constraints adhered to.

Navigation and Positioning

top engineering colleges

Problem Definition : Designing a Hand-held device which can be mounted on vehicle to see the vehicle current location using IRNSS receiver. With IRNSS system, we can replace the GPS system by developing independent navigation system using IRNSS.

Methodology: In this proposed research we intend to develop a handheld device with display showing the latitude and longitude map of a given area, further used for navigation and positioning. The research conduct is followed by field survey, data collection and analyzing of real time raw data received from IRNSS receiver, interfacing of devices like TFT and IRNSS receiver, storage, processing and filtering of received raw data and design of latitude and longitudinal graph, displaying co-ordinates on graph, designing navigation and positioning system.

Outcomes : The team attempted and succeeded with observing the latitude, longitude and altitude values of specific hotspot locations by moving from point to point with IRNSS User Receiver setup carried out during the field survey. The observations noted for each specific location and are plotted on an expected latitude and longitude map. The location values of hotspots by IRNSS is shown on latitude and longitudinal map.

Image Processing

Problem Definition : Medical Images is one of the major concerns of image processing where the efficiency and accuracy both are required at very high level. Lot of work is already done in this area related to medical image segmentation, colorization, abnormality detection etc. Even then because of requirement of high accuracy it is the open research area. Brain tumor is a life threat disease so required high accuracy diagnosis and best treatment

Methodology : The system should be able to process MRI multi slice sequences, it should be able to obtain tumor region with precise boundary from the pre-processed image. The region should be segmented to extract the texture features using GLRCM-CSLBP hybrid texture feature. Classifier should compare and identify the tumor with high accuracy. Finally it should classify the tumor region as malignant or benign

Outcome : Brain tumor detection is very sensitive and difficult task and helps in directing the radiologist for tumor detection. In this work, an effectiveness of two texture analysis method is used for identifying the tissue region of brain tumor. The proposed approach implements a novel procedure which uses a combination of GLRLM and CS-LBP texture feature and ANN classifier for the detection of brain tumor from MRI scan image.

NavIC lab

Under a Memorandum of Understanding (MoU) between Space Application Centre – ISRO and Jain University. ISRO has provided 3 NavIC/ IRNSS receivers for experimental research work for the benefit of students and research teams at both Electronics and Communication and Aerospace Engineering departments.

These receivers are capable of receiving data from all the satellites of the NavIC constellations as well as Global Positioning System (GPS) satellites.

The receiver is being continuously operated from JGI campus and recording data 24x7 for various research applications. These data are also being sent to ISRO for their analysis. Further the data are being used for space weather, performance of receiver as well as satellite and weekly reports are being generated and sent to ISRO.

In response to Announcement of Opportunity under the NavIC/IRNSS GAGAN utilization program department of Electronics and Communication Engineering has awarded 4 research projects amounting to more than Rs. 45 Lakhs funding from ISRO.

The projects address several topics in navigation, space weather and remote sensing applications. The overall vision including the receiver and project has stimulated the research capabilities of students at UG, PG and Ph.D levels.
