WIRELESS SYSTEMS AND MOBILE COMPUTING Space-Time Coding for Broadband Wireless Communications

The development of broadband wireless communication systems must cope with various performance-limiting challenges that include channel fading as well as size and power limitations at the mobile units. As a promising method dealing with these challenges, space-time coding is effective in supporting reliable, high-data-rate transmissions: the major goal in broadband wireless communications. A survey of space-time coding schemes is provided in this paper. Targeting broadband wireless communications, the focus is on space-time coding in the presence of frequency-and time-selective fading and the associated channel estimation and symbol recovery algorithms for both single-and multiuser settings.
