Abstract

High Temperature Superconducting filters combined with very low noise amplifiers of high dynamic range, exhibit very high selectivity, low insertion loss and high out-of-band attenuation. These features promise reduction of interference, better spectrum utilisation and a higher signal-to-noise ratio as compared to traditional technologies. In a CDMA cellular network these improvements are expected to provide extended uplink coverage, reduced handset power, increased capacity and improved service quality. To assess the quantitative benefits of introducing HTS technology in terms of the coverage area and the corresponding number of subscribers a CDMA Coverage Capacity Model has been developed. The model has been used for analysis of Ground and Tower mounted receivers using both conventional or HTS filters. This paper presents principles of the model as well as results of computational analyses of performance of four CDMA systems with a centre frequency of 835 MHz.
