GSM中GMSK调制信号的产生，采用了小波去噪的思想，快速扩展随机生成树算法。( GSM is GMSK modulation signal generation, Using wavelet denoising thought, Rapid expansion of random spanning tree algorithm.)

OFDM频域算法，根据WLAN前导的长训练符号完成所有对子载波的信道频率响应的简单有效的估算，这两个长训练符号内容是一样的，因此二者的平均可以改进信道估算的质量。(OFDM frequency-domain algorithm, according to leading WLAN long training symbols to complete all the pairs of channel-carrier frequency response of simple and effective estimate, the two long training symbols is the same as the content, so they can improve the average quality of channel estimation.)

用四元十字阵做被动声定位算法设计，现在是用matlab神经网络工具箱构建RBF神经网络然后仿真显示图形(With a four-element Array do passive acoustic localization algorithm design, now using matlab neural network toolbox and then build on RBF neural network simulation display graphics)

述是经典MUSIC算法的基本原理，许多限制是可以放宽或取消的。首先，关于均匀线阵的限制不是必须的，实际中可采用几乎是任意形状的阵列形式，只要满足在个独立信号源的条件下，矩阵具有个线性无关的列就可以了。其次，天线阵元在观测平面内无方向性这一点也不是必要的，而且还可以考虑三维空间的DOA估计问题，即不仅估计信号的方位角，还要估计它的俯仰角，当然MUSIC算法还用于频率、方位和俯仰的联合估计。(Above is the basic principle of the classical MUSIC algorithm, a number of restrictions can be relaxed or canceled. First, restrictions on ULA is not necessary, the actual form of an array can be almost any shape, as long as the signal source in the independent condition matrix has linearly independent columns on it. Second, the antenna elements in a plane non-directional observation it is not necessary, but could also be considered DOA estimation of three-dimensional space, that is not only estimated azimuth signals, but also to estimate its pitch angle, of course, also MUSIC algorithm joint estimation for the frequency, the azimuth and elevation.)

PTS算法，仅提供参考，欢迎交流。OFDM系统中用PTS算法降低系统的峰值平均功率比(PTS algorithm, only for reference, welcome to exchange. Reducing Peak-to-Average Power Ratio of OFDM System by PTS)

用matlab所撰寫的huffman code,裡面沒有使用matlab內建的函示,完全自己撰寫而成,使和初學者練習參考使用.(Using matlab written huffman code, which did not use the matlab built-in letter that is entirely their own written so that beginners practice and their use and reference.)
