摘　　要：当前无线蜂窝网络下行链路干扰抑制功率控制方法受限于一次处理形式,导致覆盖范围有限,误比特率增大。为了解决这一问题,文章提出了一种新的下行链路干扰抑制方法。该方法首先进行子载波分配,并采用多阶控制策略,以突破覆盖范围的限制。通过设计多阶控制形式,并结合相位连续调整技术,构建了一个高效的干扰抑制模型。实验测试结果显示,与传统的EPFD和全双工测控方法相比,该方法在降低干扰抑制误比特率方面表现更优,具有更强的可控性,能够确保无线蜂窝网络下行链路的稳定与安全运行。The current power control method for downlink interference suppression in wireless cellular networks is limited by a one-time processing form,resulting in limited coverage and increased bit error rate.To address this issue,this study proposes a new downlink interference suppression method.This method first performs subcarrier allocation and adopts a multi-stage control strategy to break through the limitations of coverage range.By designing a multi-stage control form and combining it with phase continuous adjustment technology,an efficient interference suppression model has been constructed.The experimental test results show that compared with traditional EPFD and full duplex measurement and control methods,this method performs better in reducing interference suppression bit error rate,has stronger controllability,and can ensure the stable and secure operation of the downlink in wireless cellular networks.
