Method and device for the encoding and decoding of power distribution at the outputs of a system

DETAILED DESCRIPTION To overcome this drawback, the present invention, instead of using a switch placed downline, uses a low-power distribution encoder, placed upline with respect to the amplification, and a distribution decoder for the selection switching of the output channels.
To this end, an object of the invention is a method for the encoding of distribution comprising a step for the superposing, on a signal s(t), of a piece of distribution information i(t) used for the subsequent distribution of the total power P.
