代码说明:

正交频分复用(OFDM) 是一种多个载波频率上的数字数据的编码方法。OFDM 已发展成为普遍的计划为宽带 数字通信,在无线或以上的铜导线中是否使用应用程序,如数字电视和音频广播、 DSL 上网、 无线网络和4 G移动通信。 OFDM 是基本相同的编码 OFDM (COFDM) 和离散多音调制(DMT),并且是数字多载波调制方法,使用频分复用(FDM) 计划。"编码"一词来自于

    基于matlab的模糊逻辑方面的国外资料,介绍了如何用matlab实现模糊理论。(The world we live in is becoming ever more reliant on the use of electronics and computers to control the behavior of real-world resources. For example, an increasing amount of commerce is performed without a single banknote or coin ever being exchanged. Similarly, airports can safely land and send off airplanes without ever looking out of a window. Another, more individual, example is the increasing use of electronic personal organizers for organizing meetings and contacts. All these examples share a similar structure multiple parties (e.g., airplanes or people) come together to co-ordinate their activities in order to achieve a common goal. It is not surprising, then, that a lot of research is being done into how a lot of mechanics of the co-ordination process can be automated using computers.)

  • ZF/MMSE预编码比较
    ZF预编码性能和MMSE性能的仿真,意在比较二者在相同信噪比下的不同的性能。研究者们已经找到了许多预编码的算法,我想选取其中几种不同的预编码算法进行仿真,通过基站天线数的显著增加,更直观的感受到大规模阵列天线的优点,这是其一。另外,之所以现在大规模阵列天线是主要的研究方向,是因为现在用户不断增加、无线数据业务庞大,如果应用好预编码算法,可以使得单位时间内成功传送数据的数量(吞吐量)尽可能的多,也能更深度地利用空间无线资源。为能设计出更优的通信系统设计提供数据参考,使大规模天线阵列成为日后高能效绿色宽带无线通信系统的重要技术。
