MIMO-OFDM for LTE and LTE-Advanced
There were 8 temperature and humidity sensors each of the room. The task was to create a 3D model of the flat and show the variation of temperature and humidity with respect to time.
3D modeling of temperature and humidity variation in flat
Simulating OFDM(Orthogonal Frequency Division Multiplexing ) using GNU Radio Companion
OFDM with GNU Radio
Performing real time spectrum sensing using energy detection algorithm. Tools were GNU Radio and USRP.
Spectrum Sensing in GNU Radio with USRP
Simulation of PAPR  phenomena in OFDM for different number of sub carriers (4, 8, 16, 32 and 64 ) and for different modulation schemes i.e. BPSK, QPSK, 16QAM. This was performed using MATLAB.

Experience

Research Assistant

IIIT Hyderabad
May 2010 - Present
Project Title: Mobile and Static Cognitive Wireless Sensor networks. Funding Agency: Department of Science and Technology, Govt. of India. During this work we established a Wireless Communication and Wireless Sensor Network Lab in IIIT Hyderabad campus for conducting CWSN related experiments. The Lab consists of o Wireless Communication experimentation facility using USRP (Universal Software Radio Peripheral). o Wireless Sensor Network using Memsic sensor nodes. We also proposed a doubly cognitive arch

Robotics Trainer

Edukinect
Aug 2011 - Jan 2012 (5 months, 1 day)
I worked as a Robotics trainer for EduKinect. I taught basic robotic building to the students of standard ranging from 6th to 9th in Hyderabad Public School. I used Lego MindStorm NXT kit. To my surprise the kids were amazingly more innovative and creative than what I thought. They quickly come out with several simple ideas to solve the problems. The whole experience was quite a fun.
