- The main working contents of this paper is following : 1 according to the theory of electromagnetic induction law , a new radio induction system is proposed based on the traditional radio induction technology , analyzed on its signal transmission character and its frequency spectrum character . the channel composed of the new radio induction system is compared with the parameter - constant channel and the parameter - changing channel . the application of the new radio induction system is studied in converter supply
本文的主要工作内容如下： 1在现有的无线感应技术基础上，基于电磁感应理论，提出了新型无线感应系统，分析了新型无线感应系统的信号传输特性，分析了新型无线感应系统的频谱特性，把新型无线感应系统组成的信道和恒参信道、变参信道进行了比较，研究了新型无线感应系统在变流器供电中的应用。 - It is vital for us to deal with many problems encountered in mobile communication systems by knowing clearly about the characteristics of mobile communication channels , for the mobile communication channels are typical channels with variable parameters , it is high valuable to design a simple and applied mobile channels " model
移动信道的研究与应用为移动通信开辟更为广阔的前景，认识移动信道本身的特性是解决移动通信中关键技术的前提。由于移动信道是典型的变参信道，因而设计一个既简单又实用的移动信道模型是很有实用价值。 - The underwater acoustic channel is very complex where cochannel interference , doppler frequency offsets , narrow bandwidth and time and frequency selective deep fades obstructs the development of high speed and fidelity underwater data transmissions . thus projects of high speed and fidelity underwater signal transmissions become a hotspot in the fields of world academic circles . the conventional serial communication must use adaptive equalizer to combat the multipath in real - time
海洋水声信道是一种极其复杂多变的时-空-频变参信道，其信道窄，强多途干扰，信号起伏衰落严重，一直是水下信息可靠高速传输的主要障碍，因此如何在水声信道中高速率准确地传输数据，就成为世界性的热门课题。 - So it holds a ideal ability to anti - interference and has 2 scalar level resolution in location and measuring velocity than traditional radio induction technology . and the channel composed of the new radio induction system for communication is different from the parameter - constant channel and the traditional parameter - changing channel , its parameter is decided by the mutual induction between its antenna and induction - cable , by the location of its antenna , by the signal frequency passing through , its parameter has nothing to do with the time parameter . the channel composed of the new radio induction system is a new parameter - changing channel independently of time for communication
而且，由新型无线感应系统组成的信道既不是恒参信道，也不是一般目前所知的变参信道，其信道传递函数的幅值只与信号的频率有关，与系统中天线和感应电缆之间的互感和天线的位置有关，而与时间无关，其信道传递函数的相位只与天线的位置有关，而与时间无关，由新型无线感应系统组成的信道是一种不随时间变化的新型变参信道。
