跨域通信网络中多级传输延时补偿方法研究

Research on multi⁃stage transmission delay compensation in cross⁃domain communication networks

跨域通信网络内部存在较多的传输链路,频率相同的通信载波之间在多级传输延时的过程中易生成干扰信号,导致延时补偿误差增大。针对该情况,文中提出一种跨域通信网络中多级传输延时补偿方法。根据不同域下的用户信息构建跨域认证机制,并进一步检测通信密钥状态,及时补偿缺失的数据信息,实现有效的通信信息检测。通过均衡跨域通信网络簇中的信息负载提升内部网络之间的传输交流性能,避免数据之间的模糊关系;调节通信信号衰弱因子参数,获取合理有效的补偿参数,并建立跨域信息与通信网络节点之间的关系,由此完成多级传输延时补偿操作。实验结果表明,文中方法在进行延时补偿时所需的补偿差值较小,产生的间距误差在5%以内,能够有效实现跨域通信网络中多级传输延时补偿的处理。

There are many transmission links in the cross-domain communication network,and interference signals are easily generated between carriers with the same frequency in the process of multi-stage transmission delay,resulting in the increase of delay compensation error.On this basis,a method of multi-stage transmission delay compensation in cross-domain communication network is proposed.The cross-domain authentication mechanism is constructed according to user information in different domains,the state of communication key is further detected,and the missing data information is compensated in time,so as to realize effective communication information detection.The transmission and communication performance between internal networks is improved by balancing the information load in cross domain communication network clusters,so as to avoid fuzzy relationships between data.The fading factor parameters of communication signals are adjusted to obtain the reasonable and effective compensation parameters,and the relationship between cross-domain information and communication network nodes is established,so that the multistage transmission delay compensation operation is completed.The experimental results show that the method proposed in this paper requires a small compensation difference for delay compensation,resulting in a spacing error of less than 5%.It can effectively achieve the processing of multi-level transmission delay compensation in cross domain communication networks.
