三维频率复用环境中的信道偏移指配方法

Channel Offset Schemes Used in Three-Dimensional Frequency Reuse Environments

一种新的信道指配法－信道偏移指配方法正受到越来越多的重视，这种方法能在现有的频率资源条件下，较大地提高移动通信系统的容量。本文主要讨论了三维频率复用环境中的信道偏移指配方法，详细地分析了同频复用和相邻信道使用距离，定量地计量了信道偏移系统的频谱节约效率。本文最后还通过几个实例验证了所提算法的实用性。

Channel offset schemes can highly improve the spectral efficiency of mobile radio systems.A channel offset assignment stragety used in three-dimensional frequency reuse enviroments is introduced in this paper.Some important parameters such as co-channel reuse distances and offset channel distances are computed.Spectral efficiencies in channel offset schemes are also analysed.At the end,some examples are given showing that the channel offset assignment algorithm proposed in this paper is useful.
