Abstract The number of mobile service users has been tremendously increased during the last few years, and the types of mobile services are developed from pure voice to data and multimedia services, such as audio/video streaming, e-mail, file transfer, and web browsing. These services have quite different requirements for their quality. 3G WCDMA cellular mobile networks answer this growing demand for these wireless data services. Then it needs to provide a huge capacity and wide area of coverage with acceptable quality of service. Capacity and coverage in WCDMA networks planning are the important issues because they are dependent of each other and related to the services data rate. In this thesis the capacity and coverage of mixed rate services are derived and analyzed. The uplink Capacity Coverage Product (CCP) of mixed rate services is developed by two methods, and three scenarios are assumed. The first method is the exact solution and the second method is the approximate solution. Math lap computer programs are used to get results and curves. Then some parameters affecting the mixed rate CCP are studied and a comparison between the two methods is also performed.The application of CCP in dimensioning and planning of a single service and mixed rate services WCDMA network is presented. A comparison with the conventional planning method is performed.

Abstract Most of the controllers used in industries are of PID type, this is because they have simple structure and their usage is well known among industrial specialists. The tuning of controllers is the crucial issue in the overall control loop design in order to obtain a satisfactory performance response. Over the past decades many tuning techniques were developed to adjust the controller parameters. Most of these techniques have the disadvantages of giving a combination of heavy oscillatory response, large overshoot, and long settling and rise time. This work presents a fuzzy logic-PID scheme, the basic concept behind this scheme is to combine the conventional PID controller with the use of fuzzy logic concept. The PID controller regulates the process, while the fuzzy logic part adjusts the proportional gain of the controller. This scheme will be used to overcome the previous disadvantages and to improve the performance of the conventional controller. The effectiveness of fuzzy logic-PID scheme has been analyzed through computer simulation using MATLAB. The results have been compared with those of Ziegler-Nichols, Chien-Hrones-Reswick, Cohen-Coon, Optimum PID controller and a PID with constant and variable weighting factor. This comparison has shown a considerable improvement in the performance of the transient response for different simulated processes
