Abstract
Advanced digital signal processing has the capability to modify the characteristics of a signal and to improve it. The role of digital processing techniques for wireless communication has been ever increasing. Wireless communication systems are highly complex and require a interdisciplinary knowledge from the performance of digital modulation to the channel capacity. Use of digital pulse shaping filters provides solution to many of the problems of wireless communication systems. In this paper analysis of square root raised cosine pulse shaping filter for WCDMA at a data rate of 960 Kbps for the performance of BER has been proposed. Based on the Simulink model of Matlab, this paper represents the performance of BER at constant roll off factors for number of values of group delays. The optimum value of group delay for minimum BER for two different roll off factors has been calculated.
