Power and bandwidth efficient MIMO communication techniques

Wireless/mobile communications has experienced exponential growh since the introduction of the cellular phone a quarter of a century ago. Not only does cellular phone become a necessity for many people, other wireless technologies such as wireless local area networks and Bluetooth are gradually integrated into our daily life. This increasing popularity of wireless technologies, together with advances in multi-media applications, pose a number of technical challenges for the industry: given the physical limitations on the transmit power level, spectrum, and device size, how can we continue to provide affordable devices and services to the ever-demanding consumers? A key word here is MIMO, which refers to a wireless communication technology whereby information is beamed to the user 's device via multiple transmit and one or more receive antennas. This system architecture is a departure from the traditional practice of employing only one transmit antenna. Essentially, MIMO introduces an added system resource, namely spatial redundancy, at no extra cost! Wireless systems based on MIMO technologies are expected to offer a dramatic increase in capacity when compared to conventional systems. The primary goal of this research is to devise coding and signal processing means that simplify MIMO system implementation while at the same time make them more reliable and more power/bandwidth efficient. A secondary goal is to use the research program as a platform to train highly qualified personnel who eventually will assist the Canadian industry to compete in this multi-billion dollar worldwide market of wireless technologies.
