The method for synthesis of the coordinated group DPCM codec for unmanned aerial vehicles communication systems

The new method for synthesizing the transfer function of coordinated extrapolator for differential signal transformation is described. The method is based on the methods of stability theory and does not require solving of complicated optimization tasks. Simulation was performed for the process of transmitting picture through the channel with white noise. Simulation results shows that the dynamic range of each channel is reduced in about 4 dB, while bit error ratio reduces in about 2%.
