Product input and output voltage level is based on, join groups, adjust the number of taps, winding single-phase capacity allocation, and secondary windings, the use of purification circuit.

The water-filling power allocation algorithm can achieve the maximal capacity of multiple-input multiple-output(MIMO) systems with no additional power and bandwidth consumption.

Based on reading the literature, analyzing and summarizing the current research results, the basic concepts of the water resources optimal allocation and Input-output are discussed.
