A method for improving the energy efficiency and noise immunity of multichannel systems, based on the overall coordination of channel signals, is described. To coordinate the signals, a coordinating matrix is used, whose elements are the cross-correlation coefficients of signals from different channels. The possibility of reducing the dynamic range of channel signals while maintaining the quality of communication is shown. The possibility of synthesizing invariant (with an unlimited transfer ratio in separate channels) of coordinated group DPCM codecs with channels of the same type is shown.
