Code-division multiple access (CDMA) is a channel access methods used by various radio communication technologies.
The basic principle is that differentCDMA codes are used to distinguish among the different users. Techniques generally used are direct sequence spread spectrum modulation (DS-CDMA), frequency hopping or mixedCDMA detection (JDCDMA). Here, a signal is generated which extends over a wide bandwidth.
