基于三维GIS的测控信息多任务路径传输方法

Multi-task path transmission method of measurement and control information based on 3D GIS

测控信息多任务路径调度易受多径干扰,导致均衡性较差。文中提出一种基于三维GIS的测控信息多任务路径传输方法,构建三维GIS测控信息输出信道模型,建立信道冲激响应函数,获取传输码元的空间分布信息,构建滤波器。计算均衡输出带宽和冲激响应特征量,得到相干分布源特征获取结果,利用共轭对称权值结构进行子带约束构造,完成波特间隔均衡采样和自适应调度,实现路径传输的均衡控制。实验表明,该方法输出的误码率均值仅为0.032%,抗干扰性较高,具有较好的信息调度和均衡控制能力。

The multi-task path scheduling of measurement and control information is susceptible to multi-path interference,resulting in poor balance.A multi-task path transmission method for measurement and control information based on 3D GIS is proposed.A 3D GIS measurement and control information output channel model is established,and a channel impulse response function is set to obtain the spatial distribution information of transmission symbols,and build a filter.The equalized output bandwidth and impulse response characteristic quantity are calculated to obtain the characteristic acquisition result of coherent distributed source,and use the conjugate symmetric weight structure to construct the subband constraint to complete the baud interval equalization sampling and adaptive scheduling,and realize the equalization control of the path transmission.Experiments show that the average bit error rate output by this method is only 0.032%,showing the high anti-interference line,and it has good information scheduling and equalization control capabilities.
