1.1 Introduction
While coding and signal processing are key elements to successful implementation of a
MIMO system, the communication channel represents a major component that determines
system performance. A considerable volume of work has been performed to characterize
communication channels for general wireless applications. However, because MIMO systems
operate at an unprecedented level of complexity to exploit the channel space-time
resources, a new level of understanding of the channel space-time characteristics is required
to assess the potential performance of practical multiantenna links.
This chapter will focus on experimental measurements and models aimed at characterizing
the MIMO channel spatio-temporal properties. Generally, we will define this
channel to include the electromagnetic propagation, antennas, and transmit/receive radio
circuitry, although different measurement and modeling techniques may include all or
only part of this set. When evaluating the results o ... read full excerpt from Space-Time Processing for MIMO Communications ebook
