My current research focuses are on:

  • Underwater Acoustic Communications and Networking
  • Coding Theory and its Applications
  • Sensor Network, Wireless Positioning, and Target Tracking

In the past, I have worked on a number of topics, in the general area of communications and signal processing, including:

  • Multiuser Communication
    • code design, CDMA, multi-carrier, frequency-hopping
  • Space-Time Coding for Wireless Systems
    • multi-antenna communications, diversity techniques, beamforming, limited feedback
  • Signal Processing for Communications
    • channel estimation, equalization, OFDM
