摘要

本文研究了适用于地面和卫星移动通信网络的不同码分多址方案的建模和性能评价。本文的重点是使用特定的传播信道模型和不同的解调方案对其参数的相对灵敏度。主要目的是分析在不同的传播条件下，增加的干扰水平(典型的多径环境)如何影响不同的解调器架构。本文还对RAKE接收机的传播信道模型的表征问题进行了研究和讨论

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

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.<>
