Description: THE ANTI LOCK BRAKE SYSTEM MODEL WITH WHEEL SPEED,VEHICLE SPEED AND SLIP RATIO MATLAB. Simulink are used to develop and simulate the controllers. Then, Simulink Coder, and Real-Time Windows Target are used to generate and run the resulting controllers in real time on the physical ABS system. The ABS model is the perfect tool for research and teaching at technical universities in the field of automatic control and mechatronic systems.

Description: 研究了汽车制动过程中车速、轮速等的变化过程和影响因素；以化整为零的思想，研究得到制动过程中各物理量间的微分方程关系；进而建立在ABS下的数学模型；继而通过使用simulink建立仿真模型；采取逻辑门限的控制方法，综合仿真的整个动态变化过程；得到车速、轮速、滑移率、路面附着系数和制动距离随时间的变化曲线；最后利用图像分析的方法对各物理量进行分析、比较，对比有无ABS系统下制动距离的变化，得出使用ABS控制策略能显著缩短制动距离，提高制动安全性。数据分析和处理主要应用MATLAB软件。-The braking dynamics model of quarter vehicle ABS is established. It simulates the dynamic behavior of a vehicle under hard braking conditions. We researched the change of the vehicle speed and wheel speed during the vehicle braking. According to Newton s first and second law, then dfferential equations are obtained, so we get the Mathematical model. Next the response of the system is simulated by using Simulink in MATLAB . Based on the logic threshold control, we get the curve that Speed, wheel speed, slip ratio and road adhesion coefficient and brake distance changes over time. Contrasting with ABS or without ABS , using the ABS control strategy can significantly shorten the braking distance. Data analysis and processing mainly used MATLAB software.

Description: G.729的全名Code Excited Linear Prediction Model (CELP) and Conjugate-Structure Algebraic CELP (CS-ACELP). 共轭结构-代数码激励线性预测编码.
G.729家族一共包括三个版本G.729, G.729A,G.729B,G.729AB:
G.729 是G.729的第一个版本,
G.729A 相对于G.729简化了算法.
G.729B 给G.729增加了静音压缩的算法.
G.729Ab 给G.729A增加了静音压缩的算法.
G.729属于合成分析(abs)的语音编码方法,这种方法在中低比特率的情况下可得到较好的语音质量.
编码工作于10ms的语音帧上,8K采样率,具有80个样点,,对每一帧提取CELP模型的有关参量(LP滤波器系数,自适应码书和固定码书的指针和增益),这些参量被编码和传送.在解码器中,这些参量被用来恢复激励信号和合成滤波器的参量.语音信号由激励信号通过LP合成滤波器重构得到.
注：8000Hz采样率，16位样本，压缩率为16:1，80个16位样本经过编码后为10个8位编码串；我用G.729a试过，语音还可以，音乐就不行了。另：商业应用G.729每个许可是10美元，一个许可就是一路通话；不知道现在还是不是。
