# Gigabit Passive Optical Networking

Worked on Optical Networking Terminal (ONT) software builds sanity automation
Studied on Internet Group Management Protocol (IGMP), ONT Management Control Interface (OMCI) and various systems like Voice over Internet Protocol (VoIP), IPTV, Video on Demand (VoD), Ethernet,  Plane Old Telephonic Service (POTS).

This was done as an internship for a period of two months during May-Jul’13 at Alcatel-Lucent India Pvt Ltd., Chennai.

# Studying the Characteristics of noise received by the Software Defined Radio:

This project was as the title says to study the characteristics of noise received by the software defined radio.  The received noise samples were taken and performed auto co-variance to know the noise behavior. 
                    
This was done at IIT-Madras during the fall of 2012.

#  Implementation of Amplitude Modulation on Software Defined Radio:  

This mainly aims on Implementing analog (Amplitude modulation) modulation on SDR which is new generation wireless technology.  The main challenging work was to interface the SoC processor with FPGA  and RF section of the SDR.

This work was done as an engineering internship (summer 2012) at Defence Research and Development Organization, Labs, Ministry of Defence, Govt. of India.                                          For the documentation click here

Network Topology: 
Tested the buses with various networks topologies and serial communications like I2C, UART and SPI.
 
            This work was done at IIT-Madras under IITMSAT student satellite project during the fall of 2011.

 

# Autonomous Vacuum cleaner:

This was an autonomous vacuum cleaner which sweeps the room almost more than 60 percent by the algorithm developed. This was done by atmega16 microcontroller and infrared sensors and encoders.

This was done during summer 2011 with a team of three.

#  Land Rover:
This was a simple robot operated using mobile phone and programmed microcontroller.This was done as an hobby project during the fall of 2010.
