(From XIA Leilei of CAS Key Laboratory of Underwater Acoustic Environment) Dr. ZHOU Shengli from Department of Electrical and Computer Engineering of University of Connecticut paid a visit to IACAS on May 13, 2010 and gave a lecture entitled "Progressive Inter-carrier Interference Equalization for OFDM Transmission over Time-varying Underwater Acoustic Channels".

Dr. Zhou presented a progressive receiver dealing with time-varying UWA channels in his lecture. The progressive receiver is in nature an iterative receiver, based on the turbo principle. However, it distinguishes itself from existing iterative receivers in that the system model for channel estimation and data detection is itself continually updated during the iterations. Numerical simulation and experimental data show that the proposed receiver can self adapt to channel variations, enjoying low complexity in good channel conditions while maintaining excellent performance in tough channel conditions. He also introduced the OFDM modem prototype developed by their research group.
