OFDM（正交频分复用）系统以其抗多径衰落和较高的频带利用率，得到了众多领域的广泛应用。本文就OFDM系统中关键技术之一的信道估计技术进行了介绍。并分别叙述了OFDM系统和信道估计的意义，归纳了信道估计的分类，最后介绍了MMSE、LS及其改进信道估计算法并仿真出结果。(OFDM（orthogonal frequency division multiplexing) has been widely used in many areas for its good resistance to multipath fading and high bandwidth efficiency.In this paper,channel estimation,which is one of the key technologies in OFDM systems,were introduced. Then we discuss the significance of the channel estimation and the classification of channel estimation.Finally,we study the algorithms of channel estimation such as MMSE,LS and LMMSE,and further get the simulation results. )

封装了windows操作串口的几个API（CreateFile， ReadFile，WriteFile，SetComState）。串口的读写设置这几个操作都可以简单地只用关键一两个参数就能实现操作。也是一个很好的例子，我写这个之前查了不少资料，感觉非常麻烦，索性发出来给新手们作个样例(Windows serial COM port access class，it includes CreateFile, SetComState，ReadFile，WriteFile，CloseFile)

说明：  本文主要从自适应调制的算法及实现出发，引入了OFDM子载波分组的概念，详细阐述了五种固定阈值算法和子带BER预估计算法的原理及实现，并在此基础上加入自适应编码，实现自适应调制与编码。(Based on the algorithm and implementation of adaptive modulation, this paper introduces the concept of OFDM subcarrier grouping, elaborates the principle and implementation of five fixed threshold algorithms and subband BER estimation algorithm, and adds adaptive coding to realize adaptive modulation and coding.)
