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.

这是一个用MTTLAB实现的OFDM调制解调系统，其中OFDM信号包括6个子载波，每个符号包括35个比特。整个系统包括线性分组编码，QPSK调制解调，OFDM调制解调等，最后得出在不同信噪比下的误码率曲线，整个系统简单明了，对初学者比较有帮助。
