随着科学技术的迅猛发展,人们对现代生活水平的要求越来越高,科技也在越来越进步,射频信号最是其中一个最突出的例子。我们都知道射频信号的领域很广泛,比如我们常见的电视,广播中。我们从根本上来分析,其实射频信号的作用就是用来传递信息的,尤其是用在无线信道中,因此在无线通道中具有很重要的作用。但是我们却面临着一个问题,那就是噪声。众所周知,噪声会破坏射频信号的传递。而由于来源广泛,噪声却又是无法避免的。就目前国内外的大环境来看,我们要做到消除噪声或者换句话说压制他我们可以查到很多文献,但是有一个明显的不足,就是各种算法,各种方式都有着或多或少不足。就我们现在的情况来看,单纯的研究射频信号的消除与压制的研究还是太少太少。所以这里我们就将深入到射频信号与噪声的实质里面去,系统的研究噪声对射频信号的不利条件,以至于我们能找到小区射频信号噪声的方法,我相信这对目前我们滴无线电的定位有着重大的意义。
With the rapid development of science and technology, people are increasingly demanding on the standard of living and science and technology are getting more and more advanced. Radio frequency signals are one of the most prominent examples. We all know the area of RF signals is very wide, such as our common television, radio. We fundamentally analyze, in fact, the role of radio frequency signal is used to convey information, especially in the wireless channel, so the wireless channel has a very important role. But we are facing a problem, that is noise. It is well known that noise can destroy the transmission of RF signals. Due to the wide range of sources, noise is unavoidable. For the current domestic and international environment, we have to do to eliminate noise or in other words to suppress him we can find a lot of literature, but there is a clear lack of that algorithm is a variety of ways have more or less insufficient. In our present situation, the research on the elimination and suppression of radio frequency signals is still too little. So here we will go deep into the essence of RF signals and noise. We systematically study the unfavorable conditions of noise on RF signals so that we can find out the method of cell RF noise. I believe this has a bearing on the location of our drop radio Great significance.
