说明：  针对LMS算法的FFE线性均衡器Matlab实现，以及性能分析。含有详细注释。(LMS algorithm for linear FFE equalizer Matlab implementation, and performance analysis. With detailed notes.)

Intermodulation or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with nonlinearities. The intermodulation between each frequency component will form additional signals at frequencies that are not just at harmonic frequencies (integer multiples) of either, but also at the sum and difference frequencies of the original frequencies and at multiples of those sum and difference frequencies.

通过matlab代码实现整首音乐的播放,是实现音乐播放的功能(Matlab code by the entire music playback, music playback function to achieve)

雷达测速与测距（加了白噪声和杂波），包括脉冲压缩、匹配滤波、MTI、MTD、单元恒虚警检测，程序注释特别详细，性能还不错！(Radar and Ranging (plus white noise and clutter), including pulse compression, matched filtering, MTI, MTD, CFAR unit, program comments in particular detail, the performance is not bad!)

针对基本快速扩展随机树(RRT)算法存在搜索过于平均、效率低下、用时较长的缺陷，提出了一种偏向目标型的改进型RRT算法。这种算法在生成随机点时以一定概率选择最终目标点作为局部目标点，使树的扩展有一个趋向于最终目标点的趋势，从而加快了算法的收敛速度，优化了规划路径(For basic fast Random Tree (RRT) search algorithm exists too mean, inefficient, long time with defects, we proposed a goal-biased improved RRT algorithm. This algorithm when generating random points with a certain probability of selecting a final destination point as a local target, enabling the expansion of the tree has a tendency to trend the final destination point, thereby speeding up the convergence of the algorithm, optimized route planning)

直接序列扩频利用与信息无关的伪随机码，以调制方法将已调制信号的频谱宽度扩展得比原调制信号的带宽宽得多的过程。(Direct sequence spread spectrum has nothing to do with the information of pseudo-random code modulated signal spectrum width modulation method will be extended than the original modulation signal bandwidth is much wider process. )
