In virtual ground mode, the highchannel will source and the low channel will sink current.
在虚拟接地模式中，高通道将提供电流，低通道将吸收电流。

In wireless link, Packet loss may caused by the highchannel bit error rate and nodes mobile, and multi-path routing and node switching will lead to reorder.
对于无线网络，信道的高误码率和节点移动等会导致丢包，多路径路由和节点移动切换等会导致乱序。

Rather than a single carrier solution, OFDM is chosen as a result that its equalizer dealing with the problem of highchannel delay spread has lower complexity.
