摘要
建立了基于载波的微型无人机超宽带通信链路模型,研究了超宽带尺度一时延移动通信信道模型,给出了符合数据传播特性的高斯脉冲波形以及直接序列超宽带尺度一时延Rake接收方法,对超宽带无人机通信链路接收性能以及误码率特性进行了分析并依据测试数据对系统进行了仿真。仿真结果表明基于我波的直接序列扩频超宽带体制适舍微型无人机通信链路进行测控和数据传输。
The UWB-MAV communication system model based on single carrier is created. The Gaussian pulse and time variable scale and time delay channel model is built and the joint scale-lag Rake diversity is analyzed in direct sequence （DS） ultra-wideband systems. At last the bite error rate （BER） of the UWB-MAV communication system is simulated. The simulation results illustrate that the DS-UWB system based on single carrier is quite suitable for the remote control and data transmission used in MAV.
