 UMTS PLT lead for all legacy (R99/R5/R6) and new features in (R7/R8/R9/R10): Responsibilities include leading the WPLT team for most comprehensive and effective physical layer validation/verification of all Qualcomm chipsets supporting all different feature sets in different UMTS released standards. Detail test planning for all the legacy and new features including CPC DTX/DRX, DC-HSDPA, MIMO featuring Cat20 and Multi-cell, HS-RACH, HS-FACH etc., adding automation support for all the new features in Qualcomm test-bench, monitoring coverage and performance metrics regularly, prioritizing and assigning issues to resolve and making sure committed timelines are met are some of the responsibilities.  Detailed validation/verification of lots of Qualcomm proprietary performance enhancing, power optimizing features. The process involves many rounds of extensive debug efforts in FW/SW/Systems domain. Co-ordinate with FW/SW/Systems team leads and most effective resource planning to guarantee timely execution and delivery. UMTS New Feature Emulation lead: Often times for faster time to market and to eliminate the risks of new design, Emulation (pre-silicon verification) is done on FPGA based platform before Chip-on-Doc (COD). Responsibilities include detail planning and validation/verification of the high risk newly designed blocks/features of the end-to-end system during pre-silicon phase.  Work in close cooperation with Systems/FW/SW teams, defining requirements for detail system level verification, logging, debug interfaces, discuss with third party vender (Agilent/Anritsu) with internal requirements and timeline so that integration with the vendor equipment can be done at the earliest.  Supporting various IODT/IOT/OTA for new features: Support various IODT/IOT/OTA for new features like CPC DTX/DRX, DC-HS, Cat20, Multi-cell MIMO with different infra vendors like Ericsson, Huawei, NSN etc.

 UBM (DVBH/ISDBT) Emulation lead (completed): Led the validation/verification effort of Qualcomm’s first Broadcast Modem (Bigbird) featuring (DVB-H/ISDB-T) in the emulation phase. Responsibilities included efficient planning and coordination between Systems/FW/SW/HW groups, sketching out detailed test plans including all the corner cases, generating test vectors, defining log packets, leading effort in crating stable and user-friendly automation platform, and detailed execution and debugging of most comprehensive verification in digital baseband (I/Q), to RxFE digital Y1Y2, and to RxRF domain. Because of this extensive pre-silicon testing, successful demo was possible in three weeks from chip in doc. 1xEVDV (Rev-C/D) Emulation lead (completed): Led the effort in emulation of Qualcomm’s MSM series to support cdma200 Rev-C/D. Completed initial level of verification before the project was cancelled by Qualcomm’s decision of not supporting Rev-C. Wrote many contributions towards the development of the standards.

Systems Engineering, Corporate R&D (Standards division)  Responsibilities included design, simulation and verification of techniques and algorithms designed for then evolving cdma systems. Actively participated towards the development of cdma2000, 1xEV, and 1xEV-DV standards. Follow the standardization process of 3GPP2 and support with technical contributions. Designed power control algorithms, blind rate detection algorithm, re-transmission combining, priority-based error correction schemes etc., and filed many patents. Many of them are already granted and the others pending.  Detailed simulation for the end-to-end solution of the Physical Layer. Worked with CDG and supported with Reverse Link simulations. Work in close cooperation with ASIC design and test team. Define new test cases for new chips and verification by test.

 Responsibilities included research on various key technologies like modem, codec etc., for satellite communications and experiments using COMETS satellite etc.

 Research on Ad-hoc networks: Designed ad-hoc network based on cdma technology.

 Responsibilities included design and development of high data rate CODEC, digital MODEM for satellite application based on concatenated multilevel block modulation code, and also to evaluate various project proposals from different companies and academia for Gigabit Satellite Project. Was an active member of the group that conducted 45Mbps ATM transmission between two facilities of SONY Pictures at Tokyo and Culver City, U.S.A, using two satellites and three fiber optic links for the first time in the world and received group achievement award from NASA.
