Ku-band and Scattering Communication Transmission Characteristics and Key Technologies for Miniaturized and Lightweight Application

散射通信作为一种超视距的无线通信手段,具有通信距离远、越障能力强、抗干扰和抗截获能力强等优势,在军事及民用通信中的应用日趋广泛。着眼散射通信小型化、轻量化应用,通过分析Ku频段散射信道传输特性,测试验证散射快衰落速率、相关时间等关键指标,开展低复杂度、易于工程实现的迭代检测关键技术、天线与收发设备一体化集成设计等研究,为新型散射通信系统研制提供技术支撑。

As an over-the-horizon wireless communication means,scattering communication has many advantages,such as long communication distance,strong ability to surmount obstacles,strong anti-jamming and anti-interception,etc.,and is increasingly widely used in military and civil communication.This paper focuses on the miniaturized and lightweight applications of scattering communication,tests and verifies the key indicators such as scattering fast fading rate and correlation time by analyzing the transmission characteristics of Ku-band scattering channel,carries out research on the key technology of iterative detection with low complexity and easy engineering implementation,and the integrated design of antenna and transceiver equipment,which provides technical support for the development of new scattering communication system.
