本工程实现了将三路合成的DSB信号用椭圆滤波器（低通，带通，高通）滤出； 其中的freqz函数，filter函数，fft函数都自己实现。 每种滤波器都分别用专门的函数分别写出，可以模块化。( This project will be three-way synthetic a DSB signal elliptic filter (low pass, band-pass, high pass) filter out Freqz function of which, the filter function, fft function. Each filter are, respectively, with a special function, respectively, to write, can be modular.)

对于大量照片求取通道内气泡长度和频率生成信息，每张都求取，计算速度较慢(For a lot of photos to strike a channel length and frequency of the bubble generation information, each have to strike, the calculation speed is slow)

完成SIMO系统盲均衡，利用改进的恒模算法，可以直接得到端正的星座图，无需额外的相位校正模块。自己编写的程序，验证可用。(Using the improved constant modulus algorithm to complete SIMO system equalization. The algorithm can obtain correct constellation directly, without additional phase correction module.)

Spread Spectrum Technique simply consumes spectrum in excess of the minimum spectrum necessary to send the data.
