normalize_DCT

基于matlab 车辆车牌文字识别功能。(Matlab-based vehicle license plate character recognition function.)

该程序描述的是数字电视地面广播中卷积交织部分.因为是卷积交织所以最后结果中出现为的数值表示该值是前一包缓冲数据的数.但针对第一包数据做卷积交织时,这些零位置上最后确实自动补零.(The procedure is described in digital TV terrestrial broadcasting in parts of Convolutional Interleaver. Convolutional Interleaver because it is so final results for the numerical value is that the previous data on the number of packet buffer. But for the first packet data do Convolutional Interleaver These zero position is indeed the last automatic zero.)

Minor modification of the function "bisect"

System damping model in simulink by a system springs, automovile

独立成分分析算法降低原始数据噪声，部分实现了追踪测速迭代松弛算法，有信道编码，调制，信道估计等。( Independent component analysis algorithm reduces the raw data noise, Partially achieved tracking speed iterative relaxation algorithm, Channel coding, modulation, channel estimation.)

说明：  实现了系统辨识的算法，Matlab实现了产生一均值为0，方差为1的噪声，给出系统辨识的效果。(To achieve the system identification algorithm, Matlab realized generated a mean 0 and variance of a noise, the effect of system identification is given.)
