search and development activities on high-speed wireless communication systems. Main challenges
in this area include the development of e±cient coding and modulation signal processing tech-
niques to improve the quality and spectral e±ciency of wireless systems. The recently emerged
space-time coding and signal processing techniques for wireless communication systems employing
multiple transmit and receive antennas o®er a powerful paradigm for meeting these challenges.
This paper provides an overview on the recent development in space-time coding and signal pro-
cessing techniques for multiple-input multiple-output (MIMO) communication systems. We ¯rst
review the information theoretic results on the capacities of wireless systems employing multiple
transmit and receive antennas. We then describe two representative categories of space-time sys-
tems, namely, the BLAST systems and the space-time block coding systems. Signal processing
techniques for channel estimation and decoding in space-time systems are also discussed. Fi-
nally, some other coding and signal processing techniques for wireless systems employing multiple
transmit and receive antennas are also briefly touched upon. |
