摘要 给出了一种新的多个无线个域网共存时自干扰特性分析模型.模型同时考虑了系统的同频干扰和邻频干扰.讨论了无线个域网的分布密度、目标网络内发射设备与接收设备之间的距离、无线传播指数、分组长度等因素对分组错误概率的影响,在此基础上得到不同条件下采用各种不同长度分组的前向数据传输速率.最后分析了无线个域网两种典型应用环境的特点,并根据前面的结果分别给出了这两种应用环境下提高数据传输速率的方法. A new model for analyzing mutual interference for multi-WPANs coexistence system is presented. Using this model and taking adjacent and co-channel interference into account, impact of distributing density of WPANs, distance between transmitter and receiver, path loss exponent, and packet length on packet error probability are discussed. Forward data transmission rates with different length packets are then obtained. Based on these analysis, methods for improving data transmission rates in two representative applications of WPAN are proposed based on characteristics of these applications.
