Abstract
Mobile networks efficiency depends on high speed and reliability of data transmission. Providing of channels resistance to interference will improve the quality of data transmission of 5th generation mobile networks. Phase-diferrence modulation (FDM), that provides higher speed of data transmission and resistance to interference, is offered in article for high speed and reliability of data transmission. Signal processing algorithms, that allow to achieve invariance of data transmission to changes of signal phase and frequency are developed. We consider construction of signals’ modulators with second and third orders FDM signals. Technical implementation of demodulator with resistance to interference are proposed. Adaptive selection of coherent or autocorrelation receiving millimeter radio waves are made in that demodulator. Using this demodulator can significantly improve the reliability of wireless communication in turbulent troposphere in SWF wave range.
