1. Post-Doctoral Research Associate [September 2003-Octoer 2004]: Smart antenna algorithms for 3G Handset and WLAN applications; MPRG Lab, Virginia Tech. Research interests include: Wireless communications with focus on smart antenna applications, Signal processing and DSP prototyping of communications systems, Software radio, WLAN, Ultra-wideband measurements and wireless communications standards.

2. Graduate Research Associate, EE Dept. at Virginia Tech: [1997-2002]:

• Participated in different wireless communications projects sponsored by ITT, NSF, Texas Instrument (TI), LGIC, Samsung and Navy.
• Algorithm development for smart antenna for wireless communication applications: Developed several smart antenna algorithms both at the transmitter and the receiver with focus on handset or WLAN devices. Algorithms have been developed for flat fading and frequency selective fading channels. Some of these algorithms have been studied for implementation in the 3G standard and WLAN applications.
• Antenna array hardware development:

Design of Virginia Tech Space Time Adaptive Receiver and Transmitter (VT-START)[2001-present]: Currently working on the initial design of a wideband Multiple Input Multiple Output (MIMO) testbed that will include 4 or more antennas on both ends of the link. This testbed is expected to characterize different propagation environments and assess performance improvement through antenna array processing for high data rate applications.

Design of Virginia Tech Space Time Advanced Radio (VT-STAR)[2000-present]: Worked as a team member in the design and development of 2-element by 2-element real-time Space-Time modem for MIMO channel measurements and verification of different transmit and receive diversity algorithms in various propagating environments. Developed custom interface boards for DSP interface and worked on TI TMS320C67 platform for algorithm implementation.

Wideband transmit diversity testbed development [2000]: Developed and demonstrated wideband transmit diversity at the handset for a two-element transmit antenna array system. This involved operating two wideband modems in synchronization to represent the transmit-array and a vector channel wideband receiver. Led a member of three to develop and demonstrate the testbed.

Handheld smart antenna testbed design [1998]: Implemented interference rejection capability at the handset for a spread spectrum signal by employing smart antenna. The research encompassed both simulation study and implementation at hardware level. The hardware implementation extensively relied on fixed point DSP programming on TI TMS320C541 and different levels of custom interface design.

• Project management

Samsung [2003-2004]: Lead the algorithm development for 2D Rake structures at the handset for WCDMA applications.

NAVCIITI [2001-2002]: Participated and managed a team of graduate students involved in algorithm development, hardware verification and propagation measurement.

ITT [1997-1998]: Demonstrated interference rejection capability with smart antenna at the handset on a DSP platform.

• Propagation measurements: Conducted various vector channel measurements at the handset, at both narrowband and wideband. Studies include measuring fading profiles, cross-correlation between antenna elements, and assessing diversity performance in different indoor and some outdoor-to-indoor environments.
• Work with Digital Signal Processors (DSP)

TMS320C6701: Implemented Space-Time processing

TMS320C541:   Implemented and demonstrated handheld smart antenna

TMS320C30:     Implemented various communications algorithms.

• Work with 3^rd Generation System: Antenna array in W-CDMA with focus on algorithms and implementations.
• Work with WLAN System (802.11b): MIMO algorithm development for WLAN applications.
• Proposal Writing: Participated in Proposal writing for smart antenna projects and space-time processing applications.

Time Domain Laboratory, Virginia Tech [1993-1995]

• Wideband measurement and characterization: Wideband electromagnetic material characterization by time-domain techniques. This involved signal processing of wideband pulses and working with state-of the-art instruments like HP Network Analyzer 8510 B, Tektronix Digital Sampling Oscilloscope 11801.
