The METRA Technology and Its Application Research
Guihua Kang · Journal of Circuits and Systems · 2003
It is believed that the technology for multiple-element transmit and receive antenna will be one of the key factors that affect the realization of high-speed broadband wireless Internet access networks in the future. From the application point of view, some typical mathematical models and the channel capacities of METRA systems in the practical environments are analyzed in detail. The schemes of design and implementation concerning two categories of important algorithms (data rate maximization and diversity maximization schemes) and several comprehensive algorithms that were recently proposed are extensively discussed, and their performances are analyzed and compared with each other. At the same time, problems that were encountered in practical applications and the corresponding solving methods are also elucidated. Finally the direction of developing the METRA technology is prospected.
