Abstract :
This paper presents an analysis of the performances of a digital mobile radio link based on DS-CDMA technique and the RAKE receiver. The adopted signature sequences are complex and characterized by different correlation properties, that lead to different performances in terms of bit error rate and spectral efficiency. Moreover, a preliminary analysis of the performances under non-linear channel behaviour and different modulation schemes is provided
