适用于AR模型的功率谱估计，包括基于Yule-Walker方法估计序列功率谱以及基于最大熵方法的功率谱估计。(AR model for power spectrum estimation, including methods based on Yule-Walker power spectrum estimation sequence and the method based on maximum entropy power spectrum estimation. )

Lamb波群速度，相速度，波长随着频率的变化(Lamb wave scpoe)

用matlab编写的程序，关于MATLAB图像处理的基本操作。(Matlab prepared by the procedure, basic operations on the matlab image processing)

单相并网逆变器，使用无源阻尼，实现并网电流波形和电网电压波形同频同相(Single-phase grid-connected inverters, using passive damping, realize grid-connected current waveform and grid voltage waveform in the same frequency and phase)

OFDM的性能仿真，绝对的好资料，在LTE和OFMDA中都有运用。(OFDM-performance simulation, the absolute good information, both in LTE and OFMDA in use.)

四种传统算法进行DOA估计,前后向线性预测、最大熵、最小模(Four traditional DOA estimation algorithm, the forward and backward linear prediction, maximum entropy, minimum norm)

这个方法有两个好处。 （ a ）虽然只是一个半径差逼近，很容易找到最高在一个小蓄电池，因为通过降低 隐平滑做的蓄电池。（ b ）在同一时间处理时间搜索减少 (Pattern Recognition and Image Procesing Group. The size of the accumulator is varied as hierarchical voting is performed. This has two advantages. [a] While the radius is only a poor approximation, it is easier to find the maximum in a small accumulator and because by means of the downsampling implicit smoothing is done to the accumulator. [b] At the same time processing time for the search is reduced.)

说明：  使用matlab时频分析中的一个demo文件 大家可以和传统的wavlet比较下(use Matlab time-frequency analysis of a demo we can document and traditional wavlet compared)
