Lattice Boltzmann Method for Poiseuille Channel 2D

OFDM信号在无线通信中会受到多普勒频移的影响，从而影响了OFDM信号的正交性，引起载波间的干扰和OFDM信号符号间的干扰，本代码先形成含有N个二进制码元的信号，而这个信号的前半部分和后半部分的信号是一样的，然后根据把这个信号调制成OFDM信号，最后接收端根据这个OFDM信号估计出多普勒因子(OFDM signal in a wireless communication will be subject to Doppler shift of influence, thus affecting the OFDM signal orthogonality, causing interference and interference between the OFDM signal symbol between carriers, the code first formed comprising N binary symbols signal, and the first and second halves of this signal is the same signal, and then the OFDM signal according to the estimated Doppler factor modulates the signal to the OFDM signal received, the last side)

一本介绍将音乐与概率知识相结合的英文原版书籍，对于研究音乐的数学模型有很重要的参考价值，对于研究提取音乐中各种参数提取的朋友们可能很有帮助。(An introductory knowledge of music and the probability of a combination of the original English edition of books, music for studying mathematical models have a very important reference value for studying music extract various parameters extracted friends might be helpful.)

实现hmm基本算法。此代码实现基本的viterbi算法。有学习功能(The matlab code implements Viterbi algorith to realize HMM s learning.)

说明：  OFDM系统是将一个用户的信息分别调制在了多个相互正交的子载波上面，对频率偏移非常敏感，OFDM同步技术非常关键，这里予以实现(OFDM system is a user' s information were prepared in a number of mutually orthogonal subcarriers above, is very sensitive to frequency offset, OFDM synchronization is critical to achieve here)
