Graduate Research Assistant 6/2012 - Present
- Investigated Delay Tolerant Networks (DTNs), to develop analytical
models to understand the Epidemic Routing protocol. (DTN Project)
- Evaluated several mathematical models using discrete time
equivalents of continuous time Markov processes as the basis,
such as jump Markov processes.
- Simulated the efficiency of the models using MATLAB.
- Surveyed established methods of blind equalization in wireless
communication systems to develop a novel “Blind receiver” for
LTE systems. (LTE Project)
- Identified several blind equalization techniques for application in LTE.
- Designed MCMA/AMA equalizer algorithm for a 2x2
MIMO-OFDM system in MATLAB. Compared performance with traditional non-blind
- Examined several existent blind channel estimation methods developed
for wireless communication systems. (LTE Project)
- Evaluating a candidate technique based on Noise-subspace
methods and investigating its performance benefits over traditional
approaches and the MCMA/AMA approach devised, to help develop an improved
version of the MCMA/AMA equalizer.
- Developing novel techniques to estimate Precoder matrix used in LTE transmission. (LTE Project)
- Implemented three different methods to estimate, at the receiver, the precoder matrix used by an LTE
transmitter, namely – Blind equalization using MCMA/AMA, Maximum Likelihood hypothesis testing and using Cluster Variance.
- Observed a favorable trade-off between error performance and computation complexity with a simplified
hypothesis testing method, compared to other techniques. Further research is ongoing.
- Developing a video-quality aware rate control algorithm for real-time video conferencing
applications, to optimize end-user experience, and reduce network congestion. (Rate Control Project)

- Propose to estimate the optimal policy using Q-learning.
- Evaluation of performance and further research is ongoing.
Graduate Teaching Assistant 8/2011 - 5/2012, 8/2015 - current
- Assisted in teaching junior level Electrical Engineering courses.
- Responsible for grading homework and midterm exams and final exams.
- Guided students through homework and additional course material at
office hours and in one-on-one discussion sessions.
- Several students observed improved performance and confidence
in homework and exams.
- Developed weekly quizzes to help students retain the class material better.
- In a survey, a majority of the students found the quizzes very beneficial.
- Analyzed the stability, rate of convergence and performance of communication systems
using control theoretical concepts, by modeling the system by linear delay differential equations.
- Investigated congestion control in Internet from a control theoretical perspective:
