Abstract:

Digital antenna arrays are of great interest to wireless communication systems. By utilizing spatial selectivity, the potential for performance improvement in wireless systems is vast. For example, capacity, noise suppression, adaptivity and flexibility may be enhanced substantially. Within this project we propose to investigate the use of antenna arrays at the base stations of wireless communication systems enabling spatial multiplexing for capacity increase. The effects of array configuration, access strategy, channel reuse method etc. should be examined. Detection and estimation are central issues in antenna array systems and research topics relevant to this project include efficient algorithms, sensitivity, robustness, calibration, complexity. We will also focus on spatial selective transmission as well as system requirements critical to this novel technology.
