现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFT/DFT,同步(时间/频率同步)和信道估计,以及频率偏移的估计等一系列代码.希望大家能从中得到你需要的东西. (Now I finally found a copy of it to the form of FUNCTION, reproduces OFDM mapping, IDFT/DFT, synchronized (time/frequency synchronization), and channel estimation, as well as the frequency deviation of the estimated range of the code. I hope that everyone will be you need.)

Finally, probability analysis, based on the chosen database, is performed and judgment whether the person is recognized is pronounced. Two different modeling techniques can be suggested for purposes of person identification or verification. The approach based on Hidden Markov Speaker Models (HMMs) with the mixtures of Gaussian distribution is text-dependent one. For this technology a speaker is described by a set of HMMs, constructing the set of speech groups spoken by that person. The speech groups may be phonemes or words [7]. The text-independent technology is rested upon Gaussian Mixture Speaker Models. For this technology each speaker is defined by only one model describing all utterances of that person. Identification in the range of both approaches is executed by evaluation of maximum a posteriori probability [7].

永磁同步电机矢量控制程序，位置与角度判断可通过霍尔位置传感器，编码器得到，其中也含有无位置传感器程序(Permanent magnet synchronous motor vector control program, to determine the position and angle through the Hall position sensors, encoders get, which also contains the program without position sensors)

利用matlab语言实现的DES算法，其特点是加入了UDP发送与接收模块，可以实现加密数据后的网络发送与接受后的解密(The use of DES algorithm matlab language, which is characterized by adding UDP send and receive modules can realize the network send and receive encrypted data after decryption post)

扩频通信系统仿真实验,　　　①传输的数据随机产生，要求采用频带传输（BPSK调制）； 　　　②扩频码要求采用周期为31的m序列； 　　　③仿真从基站发送数据到三个不同的用户，各不同用户分别进行数据接收； 　　　④设计三种不同的功率延迟分布，从基站到达三个不同的用户分别经过多径衰落（路径数分别为2，3，4）； ⑤三个用户接收端分别解出各自的数据并与发送前的数据进行差错比较。(Spread spectrum communication system simulation)
