摘要
为满足现在高速的信息传输需求,结合国内外研究现状,针对毫米波频段的传输衰减较大导致通信距离受限的问题,以毫米波通信系统为平台,设计了基于大规模阵列天线和毫米波频段的物理层传输帧结构,采用并行同步处理算法及基于格雷序列相关算法等,提高了高速通信的同步速度和同步性能,实现了毫米波远距离高速通信,经过实物实验验证,系统在5km距离上空口速率可达1Gbps。
In order to meet the current high-speed information transmission needs,combined with the research status at home and abroad,aiming at the problem that the transmission attenuation of millimeter wave band is large,which leads to the limited communication distance,a physical layer transmission frame structure based on large-scale array antenna and millimeter wave band is designed on the platform of millimeter wave communication system.The parallel synchronization algorithm and Gray sequence correlation algorithm are used to improve the synchronization performance of high-speed communication of millimeter wave over long distance.The experiment shows that the airport speed of the system can reach 1Gbps at 5km distance.
