针对 WCDMA 的资源占用式干扰技术研究与实现

摘要

针对 WCDMA 移动通信系统随机接入过程，建立了干扰模型，仿真分析了用户平均接入量对用户平均成功接入概率和系统归一化吞吐量的影响。利用系统随机接入过程透明化的特点，提出了资源占用式干扰方式，并研制了干扰原理样机。对目标小区进行了干扰试验，试验验证了该干扰方式对 WCDMA 移动通信系统具有干扰作用，能够实现以较小功率阻断整个小区用户成功接入网络。%Based on the Random Access Procedure of WCDMA,a novel jamming approach named resource⁃occupied jamming is presented.The paper analyzes the normalized throughput and the probability of user successful transmission.At last,numerical results and examinations are used to demonstrate the influence of this novel jamming approach.The results show that the proposed approach has a significant impact on the successful access of all UEs in a cell.
