为了增强通信接入网的安全性,避免出现资源浪费现象,提升通信接入网的数据传输效率,提出了一种基于MIMO技术的通信接入网数据超低延时自动化传输系统,旨在增强安全性、避免资源浪费并提升数据传输效率。系统采用MIMO-OFDM技术和空时编码,通过波束形成模块抑制干扰,并利用最小缓存控制模型优化缓存队列长度,实现数据超低延时传输。实验结果显示,该系统平均数据延时约为0.6 s,视频数据传输延时为2 s,有效控制缓存占用,适应多用户传输需求。此外,随着信道状态估计、信噪比和用户数量的增加,系统吞吐量进一步提升,证明了其在多用户场景下的适用性。

In order to enhance the security of communication access networks,avoid resource waste,and improve the data transmission efficiency of communication access networks,this paper proposes a communication access network data ultra-low latency automated transmission system based on MIMO technology,aiming to enhance security,avoid resource waste,and improve data transmission efficiency.The system adopts MIMO-OFDM technology and space-time coding,suppresses interference through beamforming modules,and optimizes cache queue length using a minimum cache control model to achieve ultra-low latency data transmission.The experimental results show that the average data delay of the system is about 0.6 seconds,and the video data transmission delay is 2 seconds,effectively controlling cache occupancy and adapting to multi-user transmission needs.In addition,with the increase of channel state estimation,signal-to-noise ratio,and number of users,the system throughput further improves,proving its applicability in multi-user scenarios.
