摘要：Signal Processing Techniques are being employed in the field of wireless communication to enhance the performance of the system. Service providers are deploying third generation (3G) wireless base stations that enable the user to surf the web, check e-mail, conduct video conferences and access a wide range of new services from their wireless devices. Underlying 3G innovations, Wideband Code Division Multiple Access (WCDMA) technology is pushing the expectations of wireless networks far beyond the previous limitations of 1G and 2G. To deliver on the promise of 3G, WCDMA system must handle the greater capacity, higher data rates and support multimedia standards while at the same time reduces the size, cost and the power consumption. The large expectations through WCDMA are based on its flexibility for multimedia capabilities and the high capacity. However, the demanded traffic grows rapidly and new capacity enhancements are required in order to satisfy the future needs. The present paper deals with Performance comparison of flipped exponential pulse (s2) with square root raised cosine (s1) for WCDMA. The aim of the present study is to select an appropriate pulse shaping family for simulation of WCDMA model at 5 MHZ the digital filtering approach have been applied for comparative analysis of two different pulse shaping families. It has been found that main lob attenuation is 1.5 in s1 family while 0.75 in s2 family aliasing is more in s2 family as compared to s1. S1 family is found to be better than s2 for the purpose of simulation of WCDMA based model at 5 MHZ.
