摘要

我们设计并实现了一种基于LP松弛公式的静态RWA问题求解算法。尽管对于RWA输入实例的大子集缺乏完整性约束，但该公式能够提供整数最优解。在静态RWA中，没有先验的信道使用知识，一旦找到解决方案，信道之间的干扰就无法避免。为了考虑相邻信道的干扰，我们扩展了我们的公式，并通过一组解析公式作为RWA的附加约束对干扰进行建模。

Avoiding adjacent channel interference in static RWA

We design and implement an algorithm for solving the static RWA problem based on an LP relaxation formulation. This formulation is capable of providing integer optimal solutions despite the absence of integrality constraints for a large subset of RWA input instances. In static RWA there is no a-priori knowledge of the channels usage and the interference among them cannot be avoided once the solution has been found. To take into consideration adjacent channel interference, we extend our formulation and model the interference by a set of analytical formulas as additional constraints on RWA.
