The degradation of code orthogonality due to multi-path propagation has a direct impact on DS-CDMA system performance. A novel approach in deriving the orthogonality factor, which quantifies this degradation, is presented. Code orthogonality factors for realistic radio channels are calculated and the results analysed. The extension of the derivation to cover down-link beamforming investigates its effectiveness in preserving code orthogonality.Citation

Cost effective UMTS transport topology optimizationThomas, Emanuel (University of Bedfordshire, 2010-08)This thesis studies the logical topology design for UMTS Radio Access Networks. The topology planning is investigated with specific focus on the transport network links of the Iub interface, which connects the Node B with the RNC. These links are considered as one of the most important economic factors for the UMTS network dimensioning. In order to satisfy subscriber demand and to cope with high bit-rate multimedia services, a large number of base stations are required in future cellular radio access networks. The radio access network thus becomes more complex and the transport resources for the Iub interface become considerably costly. The ultimate goal of this thesis is to investigate important aspects related to the topology planning of these interconnection links and to give insight into suitable choices for the network design. The formulated task proves a combinatorial optimization problem, which seems to be NP-hard. Therefore, in order to provide a comprehensive investigation on the topology design of the access network various heuristic techniques are applied and studied. In the framework of this thesis, the 3G UMTS network based on WCDMA is considered as the basic UMTS network under investigation.

Spatial diversity for wireless LANsBrito, Rodrigo; Allen, Ben; Dohler, Mischa; Aghvami, A.Hamid; University of Bristol (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2004-05)Wireless local area networks (W-LAN) are widely used as a means of providing broadband access for high-speed wireless data services. The maximization of the system performance independent of the transceiver technology and the operating environment is of utmost importance to the hotspot system designer. This paper reports on the performance of single input and multiple output (SIMO) W-LAN systems and shows that a circular array topology located at the access point provides the best performance improvement compared to other candidate technologies when operating in an indoor office environment.
