demands in terms of efficiency and performance by an
ever-increasing user community present an exciting challenge to
communication technology. These demands translate into designing
systems that have: improved spectral efficiency, efficient
bandwidth utilization, computationally economical signal
processing algorithms and high speed processing hardware. One of
the most significant technological developments of the last decade
that promises to play a key role in realizing these challenges is
wireless communication using Multi-Input Multi-Output (MIMO)
information–theoretic analysis reveals that significant
performance gains are achievable in wireless communication systems
using MIMO architecture employing multiple antennas. Efficient
exploitation of spatial diversity available in MIMO channel
enables higher system capacity and this architecture is also
regarded suitable for higher data rate multimedia communications.
Orthogonal Frequency Division Multiplexing (OFDM) employed in
conjunction with MIMO architecture also constitutes an attractive
solution for modern wireless communications systems. The
algorithms are intended to improve the real time performance of
MIMO based wireless communication systems such as WiFi and WiMax.
In this project
low complexity near optimal/sub-optimal solution to MIMO detection
will be proposed. The algorithms are intended to improve the real
time performance of MIMO based wireless communication systems such
as WiFi and WiMax. Complete MIMO architecture with RF Front End
will be established to enable real time implementation of existing
MIMO symbol Detection algorithms like ZF, MMSE, VBLAST and Sphere
Decoder along with the proposed algorithms. Work on Energy
efficient Cooperative MIMO networks will also be performed.
The key benefits
of this project are given below:
The project will
deliver efficient MIMO detection algorithms to enhance
performance at the physical layer of WLAN and WiMax standards.
This real time test-bed will provide a research platform for
indigenous development of wireless systems based on 802.11 (WiFi)
and 802.16 (WiMax).
The set up will
bridge the gap between academia and industry by providing a
platform for product-based solutions to the challenges faced by
future wireless communications.
It will give
know-how of implementing MIMO detectors in Hardware, and help in
the establishment of a test-bed for real world implementation of
efficient high performance algorithms.
