本程序本人在matlab环境中处理电控发动机中处理点火波形，方便分析点火波形从而诊断故障。(The procedure is designed by myself in the matlab environment to deal with electronically controlled engine ignition waveform, to facilitate analysis of the ignition waveform to diagnose the problem.)

数字通信中的眼图程序，可以完成对滤波器的性能进行评估(Eye in digital communication program can be completed to assess the performance of the filter)

this is a courseware of matlab,which is fit for the beginner

一种新的变步长的NLMS算法，具有更快的收敛速度和更小的均方误差(a new VSS-NLMS algorithm, convergence rate is faster and mean-square error is lower)

无约束条件的最优控制，并且举例说明程序如何运行(Unconstrained optimal control, and examples)

1. BPSK modulation of data which ever you input (default data is “MANIPAL REDDY”). 2. MANIPAL REDDY is changed into ASCII Format and into two-bit format for BPSK Modulation. 3. Chaos is used for spreading the binary bit sequence. 4. Uniformly distributed Noise is added to Spread signal. 5. After reception Chaotic Chip sequence is used to recover message . 6. Filter is used for removing spikes and noise. 7. Note the filter is used is just for showing a little realisitic picture. 8. Appropriate filter should be used. 9. The original data in binary and recovered data in binary format are compared
