我想连接系统左侧的盒子，该盒子由一条线划分为 CPU 侧和 RF 链部分。此外，我想减少 (HT)^+ 和 T 盒之间的两条最外层连接线，以显示数据在系统中被压缩。为了清楚起见，我想将两个 (HT)^+ 盒连接成一个大盒子，2 个 xhat 盒也是如此。

答案1
编辑（2）： 根据收到的评论，我现在想象了三种可能的线路分组和天线数量解决方案：
- 8条输入线，块
x和之间有4条线HT，其他块只有两条线和两根天线 - 2 x 4 输入线，
x和之间有 2 x 2 线HT，其他块只有两条线和两个天线 - 8条输入线，块
x和之间有4条线HT，其他块只有2条线和4根天线
两种可能性如下所示。我仍然不清楚每个 ADC 块是否连接两个或四个天线。暂时假设只有两个，但是还添加了四个天线的解决方案
代码进一步缩短，添加了 tikz 库chains，删除了所有绝对坐标，因此节点之间的距离由 控制node distance。所有线条的绘制都合并在重嵌套foreach循环中

现在应该很容易制作具有不同数量的线路和天线的新版本。我希望如此。
