IET Signal Processing, Volume 17, Issue 5, May 2023., 2023 An iterative least square with projection (ILSP)‐based approach is proposed to blind despreading of multiuser direct sequence spread spectrum (DSSS) signals. The channel response of the pseudo‐noise (PN) waveform is estimated first to despread DSSS signals.

Blind Multiuser Detection with Array Observations
Wireless Personal Communications, 1998 Cochannel interference is usually a major limitation to the performance of mobile wireless systems. Examples of different forms of cochannel interference include multi-access interference in CDMA systems and cochannel interference resulting from frequency reuse in TDMA systems.

Blind Multiuser Detection for Long-Code CDMA Systems with Transmission-Induced Cyclostationarity
EURASIP Journal on Wireless Communications and Networking, 2005 We consider blind channel identification and signal separation in long-code CDMA systems. First, by modeling the received signals as cyclostationary processes with modulation-induced cyclostationarity, long-code CDMA system is characterized using a time ...
