In order to increase generating electricity benefit, the powerstation would like to excavate downstreamchannel.
为了增加发电效益，拟对下游河道进行清挖处理。

In the implementation, we used the multiprocessing method in QNX to analyze the general flow chart of system, and divided the realization of dual downstreamchannel into three modules.
FEXT interference can be calculated using the NEXT interference measured between the two lines at the upstream ends of the loops and the downstreamchannel transfer function of one of the loops.
