为了降低移动通信误码率,需要对移动通信网络数据传输带宽进行准确预测,确保信道均衡。针对当前预测方法受到码间干扰影响较大、精度不高的问题,提出一种基于链路码元调频测量和信道均衡控制的移动通信网络数据传输带宽预测方法。通过构建移动通信网络数据传输的信道模型,设计匹配滤波器进行码间干扰抑制,然后采用时间反转镜技术进行信道均衡控制,通过链路码元调频测量方法进行数据传输带宽预测。最后进行仿真实验,结果表明,采用该方法进行移动通信网络数据传输带宽预测的精度较高,有效避免了移动通信网络堵塞,信道均衡性较好,从而降低了数据传输的误码率。

In order to reduce the error rate of mobile communication, it is necessary to accurately predict the data transmission bandwidth of the mobile communication network. In view of intersymbol interference influences and not high accuracy of the current prediction method, a prediction method of link symbol frequency modulation measurement and channel equalization control data transmission bandwidth based on mobile communication network is proposed. Through the construction of the channel model of the mobile data communication network, a matched filter is designed for intersymbol interference suppression, then the time reversal mirror technology is used for channel equalization control, and the data transmission bandwidth is predicted through the link symbol frequency modulation measurement method. Finally, simulation results show that using the method to predict the data transmission bandwidth of the mobile communication network has high precision, effectively avoids the mobile communication network congestion, and has better channel equalization performance, thus reducing the bit error rate of data transmission.
