Analysis of Simulation Parameters of Pulse Shaping FIR Filter for WCDMA

Abstract

Digital Signal processing techniques are being used to improve the performance of 3G systems. W-CDMA (known as IMT-2000 direct spread spectrum) is a third-generation (3G) mobile wireless technology that promises much higher data speeds to mobile and portable wireless devices than commonly offered in today's market. W-CDMA can support mobile/portable voice, images, data, and video communications at up to 2 Mbps (local area access) or 384 Kbps (wide area access). It enables several users to transmit their information over the same channel bandwidth. In the mode of transmission a trade off exists between bandwidth containment in frequency domain and ripple attenuation in time domain. It is this trade off of bandwidth containment versus ripple amplitude is considered during system design when developing a data transmission system that employs pulse shaping.
