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.

有信道编码，调制，信道估计等，可以得到很精确的幅值、频率、相位估计，应用小区域方差对比，程序简单。( Channel coding, modulation, channel estimation, You can get a very accurate amplitude, frequency, phase estimation, Application of small area variance comparison, simple procedures.)

自己写的一个关于chase算的程序，能得到最后的译码结果。主要用于乘积码和广义LDPC的译码算法上，有较好的性能。(Write a program to calculate on the chase, will be the final decoding results. Mainly used for product codes and generalized LDPC decoding algorithm, there is better performance.)
