Modeling and performance evaluation of different CDMA schemes for terrestrial and satellite communication systems

Abstract

The paper deals with the modeling and performance evaluation of different code division multiple access schemes suitable for applications in terrestrial and satellite mobile communication networks. The paper is focused on the use of particular propagation channel models and the relative sensitivity of different demodulation schemes to their parameters. The main goal is to analyze how the increased interference level, typical of a multipath environment, can influence different demodulator architectures in different propagation conditions. Some issues concerning the characterization of the propagation channel models in the case of the RAKE receiver are also investigated and discussed.<>
