In a normal communication channel, it is often desirable to concentrate the information in as narrow a region of the frequency spectrum as possible in order to conserve available bandwidth and to reduce power. The basic spread spectrum technique, on the other hand, is designed to encode a stream of information by spreading the encoded data across as much of the frequency spectrum as possible. This allows the signal reception, even if there is interference on some frequencies. While there are many variations on spread spectrum communication, we concentrated on Direct Sequence Spread Spectrum encoding (DSSS). The DSSS method spreads the signal by multiplying it by a chip, a maximal length pseudorandom sequence modulated at a known rate. Since the host signals are in discrete-time format, we can use the sampling rate as the chip rate for coding.

用于蛋白质数据生成分类数据的转换。做PSS（Protein Secondary Structure prediction)的可以参考一下。 (for protein production data disaggregated data conversion. Do PSS (Protein Secondary Structure prediction ) can be examined.)

通信里的2ASK信号的产生及分析，很不错，经典实用(Communication in the 2ASK signal generation and analysis, very good, classic and practical)

PSD of a sinusoidal signal

对一组混有高斯噪声的正弦型号进行独立分量的滤波处理并观察其效果，从而发现了独立分量分析的方法对于信号的处理是很有好处的，方法简单得到的效果也很直观(Mixed with a group of sinusoidal Gaussian noise model of independent component filtering and observe the effect, so that an independent component analysis approach for signal processing is very good, simple to get the effect is very intuitive)

说明：  如题，层次分析法的matlab程序 方便实用，尤其是针对不太熟悉matlab程序设计的人(err)

设计一超前校正环节，使得超调量为20 ，调节时间为1s。系统单位斜坡稳态响应误差为10 。并作出校正前后后的系统单位阶跃响应时域曲线加以比较。(Design a lead correction link, so the overshoot is 20 , adjust the time of 1s. Steady-state response of the system unit error of the slope is 10 . Made before and after correction and after the system unit step response curves are compared in time domain.)
