The combination of MIMO systems with OFDM has
emerged as a dominant physical layer technology in recent years. By making use of
multiple transmit and receive antennas, MIMO-OFDM systems not only
provide robustness against multipath fading impairments but also promise significant
increase in the throughput rates over frequency selective channels. Futhermore with
this technology, it is now possible to build high data rate communication
systems with reasonable receiver complexity.
of these advanthes, MIMO-OFDM has
been adopted by different wireless standards all over the world including IEEE 802.11n (WLANs), IEEE
802.16e-2005 (WiMAX) and 3rd Generation Partnership Project’s (3GGP) Long Term Evolution
Real-time MIMO-OFDM testbed is a
research initiative of Iqra University sponsored by ICT R&D Fund. Our aim is to develop a real-time testbed that can help in the design, analysis and rapid prototyping
of future MIMO-OFDM systems.
The aim of research is to
develop a flexible, real-time MIMO-OFDM testbed for research and rapid prototyping of wireless systems. Key
research areas of focus are
MIMO-OFDM physical layer research with main
emphasis on developing efficient and robust MIMO detection, channel estimation and synchronization
Development of a GNU radio based integrated SDR
framework, for both PHY and MAC, to enable rapid prototyping of MIMO-OFDM systems and network
experimentations in real-time
Cross-layer designs for co-operative MIMO
communication and link adaptation etc.
