Herein, we provide an overview of the research conducted in the project "Spatio-Temporal Processing in Wireless Communications" supported by NUTEK's telecommunications program. Spatio-temporal processing at the base stations of a wireless system can provide processing gain which may be used to extend range and improve coverage of the network and/or improve signal quality and lower terminal power requirements. Furthermore, with spatially selective reception and transmission, the capacity in wireless communication systems can be increased without exploiting additional bandwidth. We will give an overview of the results of this research project to date. 1 Introduction There is considerable interest today in finding cost efficiently ways to increase the spectral efficiency and range of wireless networks. One method of achieving this goal is to exploit the spatial dimension in the network. Current wireless systems use the spatial dimension in a rudimentary way by using a given frequency cha...
