Abstract

This paper exploits how interference suppression capability of the front-end RF filter in a cellular base station affects the performance characteristics of a dual CDMA cellular communication system. Analytical results of degradation on CDMA system performance in the presence of intersystem interference is analyzed, where the intersystem interference is caused by intermodulation between two neighboring channel signals associated respectively with the two competing cellular service providers in a given geographic area. Because of user mobility and CDMA power control, such interference introduced by the rival system cars can be very significant at the cell site receiver and drastically impacts the performance. The superior intermodulation suppression ability of a high-temperature superconductor (HTSC) RF front-end filter at a CDMA base station receiver is shown to be critical for the system performance in this paper.
