| Abstract | Abstract:- One of the main challenges when implementing the future mobile multimedia networks is the cost effective network evolution from second to third-generation systems. This evolution may include the use of different technologies at the same frequency band. In this paper, the performance of the Frequency Diversity Spread Spectrum (FDSS) uplink is studied in the case when there is IS-95 interference sources in the adjacent frequency. A simple analytical method which study the effect of the adjacent IS-95 on the uplink capacity of the FDSS system is studied assuming collocated base stations of both systems. The FDSS transmitter and receiver models are shown. A model to calculate the interference as a function of the IS-95 users is presented. Some numerical examples are given. It is noticed that the interference effect is high for frequency separation of 1300 KHz or less. The effect of the IS-95 system is quasi null when the frequency separation is higher than 2500 KHz. The effect of the IS-95 systems increases with the increment of its user and with the reduction of the power ratio of the received signal of both systems. |
