Abstract
The increasing demand of bandwidth from new network services has reached mobile
technologies. Multiple-input multiple-output (MIMO) High-speed downlink packet
access (HSDPA) can be the answer to this demand, being able to double the data
rate of its predecessor single-input single-output (SISO) HSDPA. The optimization of
mobile network is seen as an important issue from network operators, which see the
opportunity to reduce costs by optimizing their networks through simulations. This
thesis presents an overview of the main characteristics of enhanced MIMO HSDPA,
describes the basic MIMO HSDPA link-level simulator we built and consequently
focuses on the common pilot channel (CPICH) and its optimization. Furthermore,
we derive a computationally efficient improvement, of the a link-measurement model
utilized in a MIMO HSDPA system-level simulator, to take the effects of CPICH power
variation into account.
