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.
