dc.description.abstract	This paper presents the theoretical anti-jamming performance of adaptive multiuser DS-CDMA system with imperfect channel estimation in flat fading channel environment. Pilot symbols are used to estimate the fading coefficients using Least Mean Square (LMS) algorithm. Further, pilot data are added to users' data. Slow switching pulse noise jammer is considered in the work and the effect of imperfect channel estimation on Bit Error Rate (BER) is studied. It has been shown analytically that channel estimator reduces the phase distortion produced by channel, whereas amplitude distortion remains unaffected. Under the perfect synchronization assumption, probability of error in closed form is derived.	en
