为了提高磁感应通信系统的通信距离,采用电共振方法进行改进,将其简称为MIC通信,分析MIC的信道特征并与传统的磁感应通信进行对比.研究表明:电共振方法可以减小磁感应通信系统的路径损耗和误码率,进而增加传输距离;线圈的Q值和半径越大以及线圈内阻越小,信号的传输距离越远.
Based on electric resonance technique,this study presents a new communication system (MIC) to improve the communication range in magnetic induction communication system.The channel characteristics of MIC were analyzed and compared with traditional magnetic induction communication systems.The results show that the electric resonance can reduce the path loss and bit error rate,and therefore increase the transmission range.It is also noted that by increasing the Q value and the radius of coil,the resistance of coil is reduced accordingly,resulting in enlarged signal transmission range.
