摘要
针对多波束卫星移动通信系统的特点,分析了多波束卫星移动通信系统与地面蜂窝系统同频干扰计算方法的差异性,考虑了接收终端和波束中心卫星天线方向夹角带来的增益量的衰减,提出了适用于该系统的同频干扰算法,建立了适合于本系统的同频干扰分析模型。计算得到的载干比可以作为资源规划的反馈参考,为资源规划做出指导,满足更高的通信质量要求。
Based on the characteristics of multi-beam satellite mobile communication system,the paper analyzes the difference between theco-frequency interference calculation methods of multi-beam satellite mobile communication system and cellular system. The gain attenuation brought by the angle formed by the receiving terminal and the beam center with the satellite antenna is taken into account. A co-frequency interference algorithm and aco-frequency interference analysis model adapted to the satellite system are introduced. The carrier-to-interference ratio can be used as a reference of carrier optimization to satisfy higher requirement of communication quality.
