本文考虑了蜂窝通信系统中固定信道分配模式的邻道干扰和同道干扰的影响。彻底考虑到在相邻信道，包括直接相邻以及非直接相邻的信道中的发射所产生的干扰。一个近似的数学分析，允许一个更完整的计算的中位数移动到基地和基地到移动的信号干扰比已经可用。确定关于性能测量具有规律性属性的小区频率分配的模式。公式推导出替代小区/频率分配的信号干扰比性能的比较。>
The effects of adjacent channel interference, together with cochannel interference, for fixed channel assignment patterns in cellular communications systems are considered. Thorough consideration is given to interference produced by emissions in neighboring channels, including immediately adjacent as well as nonimmediately adjacent channels. An approximate mathematical analysis is presented that permits a more complete calculation of the median mobile-to-base and base-to-mobile signal-to-interference ratios than has been available. Patterns of cell frequency assignment that have regularity properties with respect to the performance measures are determined. Formulas for comparison of signal-to-interference-ratio performance for alternative cell/frequency assignment are derived. >
