Abstract
New emerging space-time processing technologies promise a significant performance increase of wireless communication systems. The particular application and scenario strongly influences the amount of possible performance and capacity increase if antenna arrays are deployed at the basestation (BS) and/or at the mobile terminal (MT). The achievable gain is mainly determined by the spatial correlation properties of the underlying physical transmission channel.
This paper analyzes the spatial correlation properties for various scenarios and investigates the procuring requirements for designing apace-time optimum receivers. One aim is to reduce the spatial signal dimension to the information bearing components applying orthogonal transformation techniques. It will be shown that even for virtually uncorrelated spatial channels which are characterized by high delay and angular spread, the spatial dimension can be reduced significantly. This enables less complex receiver structures and more robust channel estimation techniques.
