"Array-Like Runtime Reconfigurable MIMO Detectors for 802.11n WLAN: A Design Case Study,"
IEEE Asia and South Pacific Design Automation Conference (ASPDAC), Yokohama, Japan, Jan 19- 22, 2009.
Future high speed wireless standards such as 802.11n involve
Multiple Input Multiple Output (MIMO) antenna systems as a key
technology component. Efficient design of the MIMO detector is a
challenging task. This is further compounded by the fact that
802.11n standard requires support for runtime switching between
different modulation schemes (or modes). While searching for an
appropriate architecture attention must be paid to application
requirements such as required throughput,limits on latency, and
reconfiguration between various modes of operations. Important
hardware design metrics such as area/power should be optimized over
all the operating modes of the detector. In this paper we carry out
extensive architectural space exploration to address the issues of
power consumption,area, and reconfigurability between different
modes of operation while meeting the standards throughput
requirement. Ultimately, we come up with two designs that target
low area and low power respectively. We also maintain close to
optimum Bit Error Rate(BER), which is vital for any wireless
system. The design estimates are based on 45nm technology library.
