Abstract： In order to solve the problems of poor cognitive ability， reconstruction ability and decision?making ability in the traditional wireless communication spectrum resource allocation system， a new spectrum resource batch cooperative allocation system based on big data is designed. In this scheme， the system′s hardware structure is improved first， and then on the basis of the overall architecture of the system hardware， the local sensor， spectrum signal conditioning unit， data acquisition unit， system host and other major components are designed. The conversion of spectrum resources is realized by high?frequency current sensor. The spectrum resource signals collected by sensors are amplified and denoised by means of the signal conditioning unit. On the basis of hardware improvement， the functions of the system software is optimized in combination with big data technology， and the acquisition module， wireless communication spectrum resource analysis module， allocation module and database storage module are designed to realize the cooperative allocation of spectrum resource data in batches. A contrast experiment was carried out in comparison with the traditional method. The results show that the cognitive ability， reconstruction ability and decision?making ability of the improved system have been greatly improved， and the system has a very broad application prospect and value in the field of radio technology.

目前使用的认知无线电技术都是利用无线频谱资源实现对周围环境的分析[1]。在研究无线频谱资源之前首先要了解认知无线电，认知无线电又被称为智能无线电，能够利用无线终端分析当前所处环境状况，不断改善自身内部传输参数，确保通过最佳的参数完成传输[2]。

无线通信频谱资源分批协作分配系统是认知无线电的重要组成系统之一，通过对外界环境的感知，改变传输功率、载波频率、调制技术等参数，从而对无线通信频谱资源进行分配，提高资源的利用效率[3]。……
