Wireless Communications

· Channel estimation and equalization

· Adaptive antennas and SIMO / MIMO systems

· Algebraic and subspace methods

· Linear multiuser receivers and performance evaluation

· Precoding/decoding design in single-/multi-user MIMO systems

· Soft-iterative (TURBO) receivers

· Opportunistic scheduling in broadcast MIMO channels

· Min. energy scheduling in ad-hoc and Wireless Sensor Network

· Radio localization of moving terminals using WiFi and UWB

Active (hot) projects are currently in the following areas:

• PHY-layer scheduling for HSDPA
• Multiple antennas systems (receivers and transmitters) for IEEE802.16 (WiMAX)
• Channel aware scheduling and MAC for IEEE802.16 (WiMAX)
• Cooperative transmission for Wireless Sensor Network (WSN)
• Collision models for performance analysis (adaptive antennas in CDMA, TH-UWB, OFDMA)
• Distributed synchronization (...the problem of the sync. of fireflies applied to ad-hoc networks)
• NEW : Wireless Geophone Network (WGN), a new application of the concept of WSN…see the link

Other scientific interests ... the topics I think about when I have some spare time

Electromagnetic propagation in random media
Optical signal processing (e.g., optical equalization)
