Abstract

A model of the personal communication system (PCS) employing code division multiple access (CDMA) is presented and analyzed. In the analysis, the effect of multipath transmissions that are usually present in the portable environments is included. This effect causes severe fading degradation in the received signal power. The model introduces the factors that mostly affect the reception of different signals at the base station, and their effect on the received power is discussed. The performance of the system is measured by the probability of error and the increase in the amount of power (the power cost) necessary to overcome multipath fading effects. Upper bounds on the probability of error are obtained to show the limits on the performance
