Abstract:This paper provides an introduction to Code Division Multiple Access (CDMA) communications, which is a form of Direct Sequence Spread Spectrum communications. CDMA is a major protocol in wireless communications, which allows multiplex signals by assigning different codes to each subscriber to access the same bandwidth. It elucidates the important role played by this technology in providing better access to many subscribers at a time in wireless communications. In this presentation, the major difference between time division and frequency division multiple access (TDMA and FDMA) and CDMA techniques is emphasized graphically. The technical aspects involved in synchronous CDMA and asynchronous CDMA are discussed briefly. The advantages and disadvantages of CDMA techniques over GSM, which is another major technique used in mobile communications. The paper also gives a briefing about the history of the CDMA along with the techniques used by CDMA, like soft hand-off. Finally, it outlines the major applications and the emerging trends in CDMA technology such as wideband CDMA and CDMA2000.
