My research
interests lie in the general field of wireless communications and
networks. This includes
cooperative diversity,
cognitive radio, MIMO systems, multiuser diversity,
error control coding, coded
modulation, adaptive modulation, iterative receivers, channel estimation, OFDMA,
spread spectrum techniques and interference modeling and analysis of
wireless networks. I have strong interest in the design of communications networks under
practical assumptions.
Examples include the design and analysis of
relay cooperative networks, cognitive radio networks and coded
communication systems for fading channels, the tradeoff between diversity and
channel estimation in practical communication systems, coded
bit-interleaved modulation and coded OFDM systems with finite
interleaver sizes, diversity schemes with channel estimation errors,
directional antennas under interference conditions, layered steered
space-time coded systems, wireless sensor network prototyping with
energy-efficient medium-access protocols, the design and analysis of low-complexity
distributed estimation schemes, as long as dual-hop wireless networks in
interference and fading channels. |
