Abstract :
An higher order statistics (HOS) based analysis of the non-Gaussian characteristics of the DS/CDMA global noise and a non-Gaussian evaluation of the expected BER, in few-user systems with complex signature sequences, are performed. Different error-rate performances provided by binary Gold and four-phase even-odd equivalent-Gold (EOE-Gold) spreading sequences are also considered
