在蜂窝移动通信系统中,为处理不同的话务量寻求一种好的信道频率配置方案,已做了大量的研究工作。但要使配置的信道频率既要实现频谱利用率高,又要没有干扰,还比较困难.本文提出一种频谱利用率高且基本上没有干扰的信道频率配置新方案,该方案将实现没有同信道干扰、小区内无邻信道干扰和不出现双信号三阶互调干扰.提出的新方案与现有的蜂窝系统信道颍率配置方案.其主要差别是计算话务量负荷时不考虑干扰。在设计新方案中是假设蜂窝系统所有小区的话务量是均匀的以及各小区的信道数是相同的.
In cellular mobile communication systems, a great deal of research work has been done to find a good channel frequency allocation scheme for handling different traffic. However, it is still difficult to make the configured channel frequency high in both spectrum utilization and interference, and in this paper, a new scheme for channel frequency allocation with high spectrum utilization and no interference is proposed in this paper, Channel interference, no adjacent channel interference in the cell and no double-signal third-order intermodulation interference.The proposed scheme is similar to the existing cellular system channel rate configuration scheme with the main difference being that traffic is not considered in the calculation of traffic load. In designing a new scheme, it is assumed that the traffic of all the cells in the cellular system is uniform and the number of channels in each cell is the same.
