摘要

鉴于频谱分配的可用性和干扰条件，通过将认知用户组成的网络描绘为图，以图论模型推动频谱分配最优化是当下认知无线电频谱分配研究的重点。无干扰分配矩阵用以记载频谱分配的终极策略，但对其直接编码，往往存在编码维数过高问题。为更高效地对认知无线电频谱分配仿真建模，将可用性矩阵进行提取并编码，压缩为一维矩阵，优化完成之后再根据原有关系复原，更好地降低了编码维数，缩减了解的空间维数。实验表明，该方法能更高效、快速地完成无线电频谱分配仿真建模。

Abstract

According to the availability and interference conditions of spectrum allocation, it is a major feature of the existing re-search to abstract the network composed of cognitive users into a graph, and promote the study of spectrum allocation by graph theo-ry. The final spectrum allocation strategy is usually recorded in the non-interference allocation matrix, but the problem of high cod-ing dimension often exists when it is encoded directly. In order to simulate and model cognitive radio spectrum allocation more effi-ciently, the availability matrix is extracted and encoded and reduced to one-dimensional matrix. After optimization, the availabilitymatrix is restored according to the original corresponding relationship, so as to better reduce the coding dimension and the spatial di-mension of understanding. Experimental results show that this method can complete simulation modeling of radio spectrum alloca-tion more efficiently and quickly.
