Abstract: This study deals with methodology proposes to measure the background noise at each cell site, how background noise impacts Code Division Multiple Access (CDMA) system performance. CDMA is a multiple access technology that utilizes direct-sequence spreadspectrum techniques. With this technology comes a paradigm shift. Contrary to the conventional FDMA and TDMA systems where noise rejection deals primarily with out-of-band noise, a CDMA system concerns mostly with in-band noise. This noise may come from self- jamming (or self-noise), background noise, man-made noise, intermodulation, or noise generated in the receiver. If one can reduce the unwanted in-band noise, such reduction translates directly into improved performance. Thus, the goal of an RF system engineer is to design a network that minimizes the amount of unwanted noise introduced into the receiver on both forward and reverse links.
