摘　　要：Ultra-Wideband(UWB)技术被认为是最适合进行室内无线定位的技术,基于能量探测的定位方法由于具有复杂度低的特点,所以在很多场合适合使用。对UWB信号在不同信道下的接收信号积分能量块的偏度、均方差、峭度、最大斜率等统计特性进行了分析研究,得到了使用偏度和最大斜率的联合参数最能反应信道特征的结论,对于研究基于能量探测的定位方法具有重要的指导意义。Ultra-Wideband （UWB） technology is considered to be the most suitable for indoor wireless location. Location method based on energy detection is low complex so it is suitable to use on many occasions. The statistical characteristics of the integrated energy block of received UWB signal are analyzed in different channels, such as the skewness, variance, kurtosis, maximum slope. The conclusion is made that the joint parameters using the skewness and the maximum slope can best indicate the channel characteristics. Thus, this conclusion has important guiding significance for the study energy detection based location method
