turbo code description document

应用背景主要是应用在电子射频、通讯等行业，例如采样中的数字本振信号、接收机的发射信号等等，还可以用做测试中做一个幅值可调的信号发生器，频率源等，为测试和设计带来很大的帮助关键技术数字信号发生器   DDS  频率可调 。运用MATLAB生成相关 的原 始数据，根据按键改 变频率 控制字，不断地累加，就可以实现频率可调。将生成的二进制代码发送给对应的DAc芯片的数据接口，通过给后端的模拟信号进行简单的硬件上的滤波，即可解决信号的高次谐波。

Polarization beam splitters and 3dB couplers are used to construct a home-made90 ° optical hybrid, by  which polarization diversity optical coherent receiver is carried out with single-ended detection.A10Gb / s oscillation multiplexed differential phase shift keying (DPSK) signal is transmitted through280km Standard single- mode fiber (SSMF) using erbium-doped fiber amplifier (EDFA) amplification, and no error bits are measured in th result.
