基于多姿势人体模型的信道研究

Study on channel of human body model based on various postures

基于人体的多姿势模型进行仿真研究,以观察姿势变化对人体的动态影响。同时提取多姿势中的幅值及时间参数进行分析,以详细分析姿势会产生影响的原因。结果表明:人体动作会对路径增益产生影响,这种变化并不会影响信道稳定性,大幅度动作具有更好的传输效率。人体多姿势的变化带来的不同信道增益遵循正态分布,可将姿势的影响认为是乘以变化的统计随机量。而路径的到达时间与路径距离成正相关,多姿势下模型仿真的多路径叠加还会出现为新的巅峰值,实务中须对此加以考虑。

Based on various postures model for human body,simulation is carried out to observe the dynamic effect of pose change on human body.At the same time,the amplitude and time parameters of various postures are extracted for analysis,so as to analyze on causes of pose influence in detail.The results show that the human motion will affect on path gain,this change will not affect the channel stability,and the large-scale motion has better transmission efficiency.The different channel gains caused by the change of human body’s posture follow the normal distribution,and the influence of posture can be considered as multiplying the change of statistical random quantity.The arrival time of the path is positively related to the distance of the path,and the multi-path superposition of the model simulation under various postures will appear to be a new peak value,which should be considered in practice.
