Konteksts: [..] CDMA (Code Division Multiple Access) is different in that it neither assigns a particular time slot for each user nor it splits the frequency among the users. It allows all the users to use the entire frequency spectrum for all the time. This is achieved by what is called spreading. Each user is assigned a unique code, which allows them to distinguish between others. The base band data is spread with this unique code and a receiver having the same code can only receive the data. The code spreads the bandwidth of the user. Code division multiple access (CDMA) is a form of multiplexing (not a modulation scheme) and a method of multiple access that does not divide up the channel by time (as in TDMA), or frequency (as in FDMA), but instead encodes data with a special code associated with each channel and uses the constructive interference properties of the special codes to perform the multiplexing. CDMA also refers to digital cellular telephony systems that make use of this multiple access scheme, such as those pioneered by Qualcomm, and W-CDMA by the International Telecommunication Union or ITU.
