Introduction<br />
UEs is presented in order to validate the trends observed in simulations. In order to obtain the<br />
results included in this chapter, the author has utilised the same dynamic simulation platform<br />
that was used in Chapter 4. For this purpose, the author designed and added the support for<br />
multiple antenna Rake receivers at the UE in the aforementioned simulation tool.<br />
Chapter 6 shifts the focus <strong>of</strong> the study towards HSDPA. The capacity gain from<br />
deploying open and closed loop transmit diversity, and/or antenna receive diversity at the UEs<br />
is evaluated under different PS algorithms. In this case, the interaction between the antenna<br />
diversity and the multi-user diversity made available by fast quality based PS is <strong>of</strong> paramount<br />
importance. The results included in this chapter have been obtained with a dynamic HSDPA<br />
network simulator that was entirely developed by the author.<br />
Chapter 7 summarises the thesis report and highlights the main conclusions <strong>of</strong> each<br />
chapter.<br />
The reader <strong>of</strong> this Ph.D. thesis is expected to have a basic knowledge about system level<br />
aspects <strong>of</strong> UMTS and radio propagation. In principle, the different chapters can be read<br />
independently, although there are some cross-references between chapters. Citations are given<br />
by a number in square brackets, referring to a section placed at the end <strong>of</strong> the thesis, which<br />
contains the corresponding references. All the abbreviations are introduced in each chapter,<br />
and a list summarising the meaning <strong>of</strong> all <strong>of</strong> them is included at the beginning <strong>of</strong> the thesis.<br />
