WCM606 CDMA Wireless Systems

Lead Faculty: Dr. Shekar Viswanathan

Course Description

Analysis of CDMA (code division multiple access) concepts, models and techniques. An overview of second- and third-generation (3G) air interfaces. Direct-sequence spread spectrum (DSSS); physical and logical channels; CDMA IS-95 call processing, diversity, combining and antennas; access and paging channel capacity; planning of a CDMA system.

Learning Outcomes

  • Illustrate the basics of spread spectrum technology.
  • Select effective code acquisition and tracking techniques based on given requirements.
  • Justify and design CDMA overlays.
  • Apply sound CDMA system design philosophies to design CDMA receivers and systems.
  • Illustrate on emerging third-generation CDMA-based mobile radio systems.
  • Contrast the existing CDMA standards.
  • Defend why CDMA has taken the mobile wireless world by storm and has become a major Second Generation (2G) technology and the dominant technology choice for Third Generation (3G) systems.
  • Identify about pseudo-random codes, their role in CDMA systems, and how they offer enhanced privacy, security, call quality, and coverage in comparison to other cellular technologies.
  • Understand how CDMA offers increased capacity and improved performance.
