In the following, we concentrate on code division multiple access (CDMA) techniques, because this specific branch of telecommunications provides several possibilities for applying ICA and BSS in a meaningful way. After an introduction to multiuser detection and CDMA communications, we present mathematically the CDMA signal model and show that it can be cast in the form of a noisy matrix ICA model. Then we discuss in more detail three particular applications of ICA or BSS techniques to CDMA data. These are a...
