OFDM
本文在分析移动无线信道衰落特性的基础上,阐述了OFDM系统的基本原理,主要研究了OFDM通信系统中的基于导频符号的信道估计问题,分析了几种经典的信道估计算法以及相关的关键技术环节。 在此基础上介绍了OFDM技术在现实中的一个应用——WLAN IEEE802.11a系统模型,利用Matlab仿真软件完成OFDM系统信号生成、噪声生成、导频插入、循环前缀、调制、解调等部分的设计,最后结合计算机仿真对系统关键技术(导频、循环前缀、估计算法)的有效性和可行性进行了全面的分析与比较。适合matlab研究(Based on the analysis of mobile channel fading characteristics based on the OFDM system on the basic principles of research in the OFDM communication system of the pilot symbols based on channel estimation problem, an analysis of several classical channel estimation algorithm and the associated key technical links. On this basis, introduced OFDM technology in a practical application- WLAN IEEE802.11a system model, using Matlab simulation software to complete OFDM signal generation, noise generation, pilot insertion, cyclic prefix, modulation, demodulation and other parts of the design, the final combination of computer simulation of the system of key technologies (pilots, cyclic prefix, it is estimated that algorithm) the effectiveness and feasibility of a comprehensive analysis and comparison. Suitable for research matlab)

画出下述情况下均匀线阵方向图
1）计算来波方向为0度方向图
2）画出来波方向为45度时的方向图
3）画出来波方向为0度，幅度取分贝数：20log***（单位为dB）时的方向图
4）画出来波方向为0度，随着阵元数的增加，当N=16，N=32时的方向图，并对方向图的变化情况进行说明(Draw the following conditions uniform linear array
1) calculation of wave direction is 0 degrees direction diagram
2) draw out the wave direction is 45 degrees direction map
3) draw out the wave direction is 0 degrees, and amplitude decibels: 20log*** (unit dB) when the direction of FIG.
4) draw out the wave direction is 0 degrees, with the increase of the number of array elements, when N=16, N=32 pattern, and the change of direction is described

KernelIoControl-OEMIoControl
The system is fully preemptible when this function is called. The kernel does no processing, but it passes all parameters directly to the function supplied by you. （当这个函数被调用的时候系统完全可能被抢占，内核没有处理，直接传递参数到你提供的函数。这个我觉得说的很别扭，估计是直接传递参数到OEMIoControl ）(The system is fully preemptible when this function is called The the kernel does no processing, but it passes are all the parameters directly to the function are supplied by you (When this function is called when the system is entirely possible to seize the kernel did not deal directly pass parameters to the function you provide. I think that is very awkward, and is estimated to pass parameters directly to OEMIoControl))
