摘要
从GEO卫星通信信道模型及卫星通信的干扰和噪声的性质入手,分析了CDMA通信容量与干扰和噪声的内在关系,特别是容量与交调干扰及扩频增益之间的关系,得出其关系式进行仿真并讨论其结果。为把高质量的CDMA通信方式应用于GEO卫星,特别是INMARSAT系统提供理论基础。
Starting with the characteristics of channel model, interfere and noise of GEO satellite communication, the interrelation of CDMA capacity with interfere and noise; especially the relation of the capacity with mix interfere and plus of expand frequency; are analyzed. Then the relation pattern is obtained to carry out the simulation and the results are discussed. It provides theoretical basis for applying the high quality CDMA communication mode to GEO satellite, especially to Inmarsat system.
