MIMO Overview
Noting
the tremendous advancements by researchers in the theoretical development
of MIMO and space-time systems in general. The UCLA approach is a unique highly practical
multidisciplinary approach specifically targeted at identifying and solving
unique challenges associated with the actual implementation and realization
of MIMO systems. The ultimate goal of the program is to develop a
complete 8x8 real-time MIMO OFDM testbed system in 2006. The testbed will
be built around unique VLSI ASICs developed as part the same research and
will be capable of achieving throughput rates of 1 Gbps. As such the work
is extremely practical in nature and consists of three main tracks as
follows:
1.
MIMO System
Design
- Algorithmic development for an end
to end system
2.
MIMO OFDM
Testbed Development
- Three phase
approach that starts with a non real-time SDR based approach and culminates
in the Gbps 8x8 system. The
testbeds will be used to validate (or disprove) theoretical results, and to
establish the practical bounds on system performance.
3.
VLSI system
research
- Investigate and develop novel VLSI
architectures that can deliver the 100's of GOPS of processing power,
required by broadband MIMO systems, with extreme power efficiency.
Historical Note
MIMO research at UCLA was
first carried out by the wireless integrated systems (WISR) group in 1999
with funding by the DARPA NGI program. The scope of the initial program was
to investigate single carrier, DFE based, MIMO systems. Since 2001 we have
been focused entirely on OFDM based MIMO systems. This work is for the most
part supported by the ONR AINS program with other funding from industry and
the NSF.
