ProjectsResearchCoexistence of LTE-Unlicensed and WiFiWith the rapid increase in the number of mobile devices and hence, the increase in the traffic loads, LTE service providers are allowed to use the unlicensed spectrum for transmission, resulting in LTE unlicensed. Since LTE utilizes the unlincensed spectrum, the coexistence with already deplyoed newtworks (WiFi) should be fair. We propose a system model and solve for a utility optimization problem using techniques from convex otpimization and game theory. We also present a q-learning based technique to dynamically determine the individual airtimes for LTE and WiFi. Tags: Matlab, CVXPY
Course Projects, Learning and FunSpeech Enhancement using Deep Neural NetsRemoving the noise present in a real time noisy signal is a challenging problem even today. With the advancements in Deep Learning, this project aims to enchane the quality of noisy signals using Deep Neural Networks. Using the log power spectrum of the nosiy and the clean sigals, the network learns the differences between them and removes the noise if a new signal is given Tags: Python, tensorflow, kerasCode: hereRed Blood Cell Counting and White Blood Cell ClassificationUsing Image processing and Machine learning techniques for Red blood cells count and disease diagnosis to improve the quality and reduce the time required for reports. Counting the number of red blood cells present in a blood smear image is done using Image processing techiques like circular hough transform and Watershed algorithms. Classify the White blood cells into its major catagories which would be useful to identify any diseases present in the blood using Convolutional Neural Networks Tags: Python, Tensorflow, Keras, MatlabCode: hereCovid-19-TrackerNumber of new cases, recovered cases, and deaths of covid-19 for each country. Includes daily cases and total number of cases till date. Interactive maps to zoom into a particular country Tags: React, FirebaseCode: hereLink: hereSmart Hand StickThis project aims using of singal processing techiques to impove the quality of visully impaired people by providing themm a smart hand stick which alerts the user about any obstacle present infont of them by sounding an alarm. Also a DC motor is connected which provides a vibration to the stick to prvent the user hitting any obstacle in a noisy environment Tags: Matlab, Arduino |
