Special Issue on Signal Processing Techniques for Space-Time-Coded Transmissions
October 2002
|
Space-time coding (STC) has emerged over the past
few years as a new paradigm for optimally combining
modulation, coding, and diversity gains over wireless
links. It is ideal for improving the downlink
performance (which is the bottleneck in asymmetric
applications such as Internet browsing and
downloading) while keeping user terminals
lightweight and cost effective.
STC was originally developed for frequency-flat
quasi-static fading channels. Extensive recent
research has focused on extending it to frequencyselective
and time-selective fading channels.
Detection of space-time-coded signals presents a
significant signal processing challenge as
multiple coded, distorted, and faded copies of
the desired signal are superimposed at each
receive antenna and corrupted by noise, multiuser
interference, and synchronization errors.
Original research as well as tutorial papers are
solicited in the general area of signal processing
techniques for space-time-coded transmission. |
