摘要:
针对传统无线地下传感器网络中的磁感应通信系统所固有信道路径损耗较大,无法满足较远距离的通信需求的问题,构建了一种基于波导技术(Magnetic induction,MI)的磁感应通信系统信道模型。通过采用波导技术,即采用一列一定数量的磁耦合的元件,向收发线圈之间等距离引入一定数量的无源中继线圈,在每个谐振线圈中引入的匹配电容的容值都应控制在大于10 pF,同时设定继线圈之间的理想距离为0.7 m,采用电共振的方法,能够有效降低整个通信系统的信道路径损耗,同时也有效地拓展了磁感应通信信道带宽。仿真实验表明:MI波导通信系统在较低噪声功率环境下,当路径损耗小于100 dB时,路径损耗值将不会影响到信道误码率。
Abstract:
In light of the fact that the inherent channel loss of the magnetic induction communication system in the traditional wireless underground sensor network is greater and can not meet the long-distance communication requirement,a channel model of the magnetic induction communication system is constructed based on waveguide technology(Magnetic induction,MI).A certain number of magnetically-coupled elements are adopted,a required number of passive relay coins are introduced between the receiving and transmitting coins,and the value of matching capacitance introduced in each resonant coil should be more than 10pF. The ideal distance between the relay coils is set at 0.7m. Using the method of electrical resonance can not only effectively reduce the channel path loss of the entire communication system,but also effectively expand the magnetic induction communication channel bandwidth. The simulation results show that when the path loss value is below 100dB,it will not have a effect on the channel BER.
