Title: Analysis And Simulation Of Interference In Code Division Multiple Access (Cdma) Wireless System
Author: Ahmed, Musa ELrayah ELemam
Abstract: To achieve the requirements of high capacity applications such as multimedia services, large coverage and large number of simultaneous users, CDMA IS-95 technology is designed. CDMA is the currently the most used technology in wireless communications and is also targeted for the third generation of wireless standards for its better spectral efficiency, better performance and easier base station placement compared to other technologies. CDMA system is interference limited and so must utilize some form of interference reduction in order to maintain an acceptable quality of services and capacity. Interference is related to important indicators of customer's satisfaction (grade of service). In this project interference in IS-95 CDMA cellular system is demonstrated, analyzed and computed using simulation (MATLAB) and analytical methods. The effects of changing number of users, processing gain, multipath delays and variance of noise on interference are investigated. The bit error rate (BER) of IS-95 CDMA is obtained by simulation. The expression of cell capacity in CDMA is given in the ideal case of perfect (APC), also expression is given in case of additional parameters.
