Employment & Research Experience

Senior Technical Staff Member at AT&T Research (Wireless Systems Division) (2001-02)

·         Lead major investigation on analysis and characterization of orthogonality factor, an important parameter in WCDMA downlinks. Results have significant implications on downlink capacity.

·         Part of a team that significantly improved an in-house WCDMA simulator, furthering internal research and potential external commercialization. Conducted a thorough system level study of WCDMA downlink channels capacity, shedding light on pertinent design and analysis issues.

·         Successfully implemented simulation engine - currently possessed by few companies worldwide - for the advanced and comprehensive COST259 general channel model, with promising research applications. Participating in 3GPP channel modeling standardization efforts.

·         Novel study of interplay between fast scheduling diversity and multipath channel diversity, and its impact on receiver design. Problem formulation has scope for promising future work.


PhD Research (1997-2000)

·         Primary focus on characterizing effect of terminal mobility and wireless channel impairments on cellular resource allocation schemes.

·         Analyzed the effect of channel estimate reliability on proposed link adaptation schemes in 2.5G EDGE systems, leading to interesting insights on a proposed no-transmission mode.

·         Analyzed the effect of terminal mobility, channel, and interference on the hybrid voice/data Packet Reservation Multiple Access protocol. Analytical technique developed extends the range of problems that can be exactly analyzed.                                 

·         Research partly done while at Stanford University as a Visiting Graduate Student Researcher. (1999-2000)


         Undergraduate Research Project (1995-96)

·         Designed, built, and successfully demonstrated hardware for Transcoder to double existing capacity of lines between exchanges in rural India.

o        Project required implementing complex hardware design, FPGA digital logic design, assembly code architecture and implementation for system control, synchronization, and monitoring. Hardware involved 8 ADSP21xx running in parallel for simultaneously compressing and decompressing 22 voice channels.

Distinctions & Awards

·         Recipient of AT&T World Leadership Award given to 36 graduates from Asia/Pacific region. (1997)

·         Awarded the Philips India prize for best undergraduate academic performance in Electronics and Communications Engineering, IIT, Madras. Also, awarded Institute Merit Prize for 2 years. (1996)

·         Secured 17th all India rank in the joint entrance examination (JEE) for admission into the Indian Institutes of Technology (IIT). (1992)

·         Secured 2nd rank (out of 40,000 candidates) in state’s engineering entrance exam (EAMCET). (1992)

·         Recipient of National Talent Search Scholarship (NTSE, India). (1992-96)

·         Stood 1st in state level Mathematics Olympiad. (1991)
