摘要
对信道参数、网络参数等认知技术进行研究,提出了一种基于信道参数、网络参数、时间和位置等信息建立多元环境认知的短波信道模型案例库的方法。通过对信道模型案例库进行索引实现短波电台快速选频建链,并对获得的上、下行建链频率进行信道链路验证;在信道验证失败时,通过大窗口、大步进的初始探测以及小步进的精细化探测获取目标建链频率;并根据选频建链的数据相应地进行信道模型案例库修正。
The cognitive technologies of channel parameters and network parameters are studied,and a method of building a case base of multi-environment cognitive shortwave channel model based on channel parameters,network parameters,time,location and other information is proposed.It realizes fast frequency selection and link building of shortwave radio through indexing the channel model case library,and carries out the channel and link verification of the obtained uplink and downlink building frequency.When the channel verification fails,it obtains the target link building frequency through the initial detection of large window,large step,and the refined detection of small step.And the case library of channel model is modified according to the data of frequency selection and link building accordingly.
