Coexistence of LTE-Unlicensed and WiFi

With 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.

Speech Enhancement using Deep Neural Nets

Removing 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

Red Blood Cell Counting and White Blood Cell Classification

Using 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

Smart Hand Stick

This 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
