Energy efficiency management of communication channels

The article considers questions of energy efficiency management of communication channels operating in a single communication system. The authors propose data transfer method in wireless networks that can be used for distribution of energy efficiency between communication channels of one communication system. The structures of transmitter and receiver are described. The authors describe a communication system of unmanned aerial vehicle where there is necessity to transmit low-speed telemetry data and to transmit high-speed payload data to ground control unit. The information of low-speed data source is modulated by QAM4 and information of high-speed data source is modulated by QAM16. Synthesized constellation is obtained by summation of QAM4 and QAM16. By adjusting the amplitude of QAM4 we can distribute energy efficiency between communication channels. The proposed method can be generalized for multichannel communication systems. Adaptive distribution of energy efficiency between communication channels allows to improve communication systems energy and spectral efficiency.
