Study on the Downlink Interference Suppression Method of Wireless Cellularnetworks
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 in-creased bit error rate.To address this issue,this study proposes a new downlink interference sup-pression method.This method first performs subcarrier allocation and adopts a multi-stage con-trol strategy to break through the limitations of coverage range.By designing a multi-stage con-trol form and combining it with phase continuous adjustment technology,an efficient interfer-ence 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 en-sure the stable and secure operation of the downlink in wireless cellular networks.
