ail 命令可用于查看文件的内容,有一个常用的参数 -f 常用于查阅正在改变的日志文件。 tail -f filename 会把 filename 文件里的最尾部的内容显示在屏幕上,并且不断刷新,只要 filename 更新就可以看到最新的文件内容。 命令格式: tail [参数] [文件] 参数: -f 循环读取 -q 不显示
1,△f = f·v·cosθ/c,f表示载波频率,5G/B5G朝着毫米波等高频段方向发展,因此多普勒拓展的影响将更显著。此外,Masssive MIMO的现有规模已达256维度,并将朝者上千的规模发展。值得注意的是,MIMO系统若要在容量上随天线数增加而线性递增,准确的信道估计必不可少。因此,时选信道的研究具有很
