Abstract: The introduction of GPS (Global Positioning System) in modern guidance system has revolutionized the world of navigation in land, sea, air and even in space. This work deals with one of the most familiar implementations of GPS which is determining the direction of a moving object with respect to a reference point, determining the distance between this object and that point, with the ability of displaying the motion on a corresponding map. This project is done by making an interaction between the hardware and software parts.

Abstract: In this thesis, an overview of traditional multiple access techniques were presented. Advantages and disadvantages of each system were outlined. A classification of CDMA systems was given. The DS-CDMA was analyzed and a formula for evaluation the BER performance of the system was given. Three modern CDMA system were discussed, namely, Directsequnce-CDMA (DS-CDMA), Multicode CDMA (MC-CDMA) and Multicode-Multicarrier-CDMA (MC-MC-CDMA). The three systems were analyzed and formulas for evaluating the BER performance of the three systems were given.

Abstract: This thesis presents an FIR digital filter design, simulation and FPGA based implementation. Due to the importance of FIR filter in DSP, FIR filters can create transfer functions that have no equivalent in linear circuit technology. They can offer shape factor accuracy and stability equivalent to very high-order linear active filters that cannot be achieved in the analog domain.
