Abstract :
In this paper, the performances of DS-CDMA communication systems with the band limitation and narrow-band rejection filters are investigated. We assume that the ideal filter and the filter constructed of a cascade connection of the 7 numbers of the first-order Butterworth filter are used as the band limitation in the system transmission line. And, using the ideal and the prediction error filters, we show the limitation of the bandwidth of the interference wave.
