Multi-antenna Techniques in Ultra Mobile Broadband Communication Systems
May 05-May 08
ISBN: 978-0-7695-3135-9
Theoretically, multi-antenna techniques offers significant capacity benefits, but realizing these gains in deployed wireless systems remains a very challenging problem. MIMO has been used in wireless LAN systems with great success. However, due to the hugely varying spatial profiles and velocity patterns of the Access Terminals, integrating MIMO techniques in a wireless WAN system has been a difficult design problem. This paper introduces the design paradigms of Ultra-Mobile Broadband, which is poised to become the successor of EVDO as the next generation of high speed wireless system. UMB allows the use of MIMO in various forms to suit the deployment scenario, and elicit as much gain as possible.
