Wireless Communications

Wireless research areas

• Communication theory, information theory, signal processing, control theory, optimization theory  (squeezing more capacity from available resources)
• Physics: 
  • Electromagnetic physics (understanding wireless propagation)
  • Device physics (making better RF, DSP chips)
• Networking and queueing theory (designing efficient, reliable, secure protocols)
• Applications: multimedia, software development, marketing, business models, game theory (designing revenue-generating services and applications).

Some topics:

1. Resource allocation optimization for multiuser OFDM
2. Space-Time Coding, Smart Antenna Techniques
3. Multiuser Detection (MUD)
4. WCDMA
5. Adaptive/Blind Techniques (Equalizer/Estimation/Detection)
6. OFDM (Coded/Uncoded)
7. Turbo Code
8. Ultra WideBand (UWB) Wireless Communication
9. Software Radio
10. Quantum Communication
11. Ad hoc networks
12. 4G wireless networks
    • 2G/3G migration to fourth generation networks
    • Interoperability and interconnection between heterogeneous networks
    • Network architectures and protocols for fourth generation networks
    • Location aware services and applications in fourth generation networks
    • Management techniques for 4G networks (traffic, mobility, location, QoS, etc.)
    • Physical layer enhancement for fourth generation networks
    • Seamless roaming between satellite and terrestrial networks
    • Support of previous generation infrastructure in fourth generation networks
    • Role of Internet and its interconnection in fourth generation wireless networks
