• Design and develop scalable DSP software modules for various features on multi-core DSP/GPP using C/C++

• Develop unit test framework using Matlab and C++ for the software modules and unit test extensively

• Participate in algorithm/feature design reviews and implement DSP software for algorithms/features efficiently

• Integrate and system test the features on the system and validate against the system test specification

Teaching assistant for an advanced computer networks course

• Develop test plans for functional and system level characterization to evaluate HW performance of smart wearbles.

• Work closely with cross-functional teams in CTO organization to review solutions and drive vendors to upgrade hardware to meet target KPIs.

*** Cellular Networks/ RF planning :

• Developed a network planning and optimization software tool for managing GSM/UMTS cellular networks with extensive QoS analysis for improving radio network quality and OPEX efficiency.

• Investigated the cause of KPI failures in a dense cellular network and designed algorithms to perform root cause analysis of RF issues to meet target KPIs.

• Developed a software tool for automated OSS based network diagnostics, fault tracing, traffic analysis and extensive QoS analysis by targeting KPIs. Worked with a team of RAN engineers to design, develop and deploy the tool in the network and analyze system quality, functionality, and performance. Pilot testing involved deploying the tool to multiple cities.

**** Physical (PHY) layer waveform design :

• Designed a physical layer waveform for a CDMA based robust hybrid spread spectrum (DS-FH) based data link. Analyzed trade-off in performance versus complexity and feasibility for implementing adaptive equalization, convolutional codes and signal detection for MIMO systems.

*** Sensor Netwoks :

• Investigated the design of a wireless link to support transmission of images and small sized video using TELOS B motes on TINY OS platform.

• Implemented a multi-hop relay network to transmit sensor information from a source node to a destination sink.

* Designed and developed high frequency microstrip patch antenna structures for wireless applications.

* Performed RF Survey/ planning and testing for deploying antennas structures at client sites.

* Designed a linearly polarized edge-fed rectangular microstrip stacked patch antenna for GPS applications.
