A method of converting a series of stationary ergodic sources, leading to the construction codes nonequiprobability codewords. Based on the introduction of the minimum redundancy obtained construct, allowing using a simple one-dimensional signals to obtain the increment of the energy efficiency of data transmission systems (IMS). At the same time, the received code-signal constructions are close in characteristics to ensembles of biorthogonal signals, but they provide substantially better band efficiency. A comparison of the developed constructions with known methods of reducing unit costs in terms of frequency and energy efficiency. The article shows the possibility of using concatenated code-considered signal constructions with any method of block or convolutional coding, which provides an increase in the energy gain of the corresponding codes by 1,3 …3,2 dB.
