Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

matlab仿真的直接扭矩控制，模型参数没有调出来，给大家看看。(Direct torque control matlab simulation, the model parameters do not tune out for everyone to see.)

数字图像处理中的小波去噪代码！ 希望对大家有用 matlab(Digital image processing in the wavelet de-noising code! Want to be useful to everyone matlab)

matlab程序，可任意生产波形，包括正弦波，谐波或者叠加的n次谐波，也可产生mif文件 (matlab procedures, arbitrary waveform production, including sine wave, or a superposition of harmonic n harmonics can produce mif file)
