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.
