چکیده
Recent research interests in the field of wireless personal communications have been moving to the third-generation cellular systems for higher quality and variable speed of transmission for multimedia information. Spatial and temporal signal processing based on an antenna array will become a breakthrough technique for the cellular systems. In order to design and analyze an antenna array, a radio propagation model should be modeled in both the space and time domains, while traditional communication theory represents it as a delay profile in the time domain. The spatial characteristics (i.e., the angular profile) are important as well as the temporal ones. In this paper research activities on smart (array) antenna signal processing, spatio-temporal radio channel modeling and antenna design in Taiwan are introduced.

Node Throughput Analysis of Decentralized Wireless Networks Using Multibeam Antennas in Multipath Environments
The use of multibeam antennas (MBAs) in decentralized wireless networks significantly increases the throughput by improving spatial reuse and extending coverage compared with single-beam antennas. The throughput performance may, however, degrade in multipath environments due to the fact that multipath propagation increases the probability of collision among different users. Based on the probabi...
