移动无线电系统中的频率分配过程通常旨在实现互调兼容性的测量，并且原则上，只要有足够数量的可用信道并且可以以最小的限制进行分配，那么该目标是可以实现的（至少就三阶产品而言）。然而，在蜂窝系统中，由于需要将小区中心基站发射机多耦合到公共天线上，因此施加了额外的限制，并且该要求对小区中心的最小频率间隔设置了下限，这反过来又使得实现三阶兼容频率规划变得极其困难。本文研究了三阶兼容性的最小频率间隔与可用信道数量和小区簇大小之间的关系，以确定最佳配置。
Frequency assignment procedures in mobile radio systems generally aim at achieving a measure of intermodulation compatibility, and, in principle, provided sufficient numbers of channels are available and may be assigned with the minimum of restrictions, then this objective is achievable (at least as far as third-order products are concerned). However, in cellular systems, additional constraints are imposed by the need to multicouple cell centre base station transmitters on to a common an tenna, and this requirement sets a lower limit on the minimum frequency separation at cell centres, which, in turn, makes achievement of third-order compatible frequency plans extremely difficult. The paper examines the relationship between the minimum frequency separation for third-order compatibility and the number of available channels and cell cluster size, in order to identify optimum configurations.
