Effect of Group Delay in WCDMA based Pulse Shaping Filter using Discrete-Time Eye Scope

TLDR: The present paper deals with Effect of group delay in WCDMA based pulse shaping filter using discrete-time eye scope.

Abstract: The application of signal processing techniques to wireless communications is an emerging area that has recently achieved dramatic improvement in results and holds the potential for even greater results in the future as an increasing number of researchers from the signal processing and communication areas participate in this expanding field. Today, wireless multimedia is moving from vision to reality. Service providers are deploying third generation (3G) wireless base stations that enable the user to surf the web, check email, conduct videoconferences, 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 Effect of group delay in WCDMA based pulse shaping filter using discrete-time eye scope.
