英文摘要： The high-efficient communication theory and method are the current research frontier in mobile communication systems and RF strealth of communication signal.Based on the related research of the phased array, the project will focus on the method and theory that can concentrate transmitted signal energy on arbitrary spatial region with the FDA beamforming, and study the applications of these theoretical methods for software cell allocation, multi-user communications and RF communication signal stealth in modern mobile communication systems. Therefore, the research contents mainly include: (1) study on the theory and method of transmission beamforming which can concentrate transmitted energy in certain region for FDA; (2) study on the method of communication signal waveform design, effective modulation, and multiuser communication based on FDA; (3) study on the effective detection, demodulation and information recovery of the communication signal for FDA, including the carrier and symbol synchronization, equalization method and so on. The research results can provide technical support and options for 5G communications system as well as solid theoretical and application basis for national communication industry upgrade, and an effective method and technology for special stealth defense communications.
