CDMA – Code Division Multiple Access

نویسنده

  • Robert Pierce
چکیده

Code Division Multiple Access (CDMA) is probably the most interesting multiple access method provided by spread spectrum technology. CDMA refers to a multiple access method in which the individual terminals use spreadspectrum techniques and occupy the entire spectrum whenever they transmit. This paper focuses on direct-sequence spread-spectrum principles (processing gain, spreading, de-spreading, modulation and codes) and more into CDMA cellular system fundamentals like multiple access interference (MAI), multipaths, RAKE receiver, power control and soft handover. Also the capacity of a CDMA system is discussed. Also CDMA applications in cellular system standards such as IS-95, CDMA2000 and Wideband CDMA are briefly introduced.
