The effect of body movement on performance of body area communication system was studied. Channel gains on body standing, making time, and running were measured in experiments. Based on the experiments' data, the cumulative distribution function of channel gain was acquired and compared with several general statistics distribution. Channel gain obeyed normal distribution. Parameters were estimated using maximum likelihood method. The mean, standard deviation and confidence interval were acquired. Then, channel statistical and simulation model has been established to analyze the system performance. Within the environment of Gaussian white noise, the effect of body movement on system performance of amplitude shift keying modulation was simulated. The general methods of body area communication channel modeling and simulation were given. Results show that Bit Error Rate (BER) increased slightly with fierce degree of body movement., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=基于准静电场的体域通信技术是一种用于人随身电子设备互连的新方法。为研究人体运动对体域通信系统性能的影响，实验测量了人体静止、踏步和跑步3种状态下的信道增益，得到信道增益的累积分布函数，与多种常见统计分布类型相对比，发现其服从正态分布，并利用最大似然方法进行了分布参数估计，得到信道增益的均值、标准差和置信区间。基于信道分布特性，建立了信道统计模型以及系统仿真模型，并进行系统性能仿真，在高斯白噪声环境下通过仿真研究了人体运动对幅移键控系统误码率的影响，给出了体域通信信道建模和仿真的一般方法。结果表明，通信误码率随人体运动激烈程度增强而升高，但变化程度不大。,
