Performance Analysis of Direct Sequence CDMA in Impulse Noise Channel

In this paper, we analyse performances of DS-CDMA-QAM (direct sequence-code division multiple access-quadrature amplitude modulation) in presence of impulse noise. This analysis is carried out theoretically and confirmed by simulation. It allows to precisely determine the reduction of the penalty induced by impulse noise on the SEP (symbol error probability) of DS-CDMA-QAM transmission
