摘要

本文提出了离散傅立叶变换扩展(DFT-spread)和2×2空时分组码(STBC)两种方法的结合，以提高极化分复用(PDM)相干光正交频分复用(CO-OFDM)通信系统的系统性能。系统的性能一般用误码率(BER)来衡量。对于64-QAM，在前向误差控制(FEC)限制下可以实现850 km的通信长度。

On the 2×2 DFT-spread space-time block code CO-OFDM for PDM optical communications

This work presents the combining of two methods, which are discrete Fourier transform spread (DFT-spread) and 2×2 space time block codes (STBC), to improve the system performance for polarization division multiplexing (PDM) coherent optical orthogonal frequency division multiplexing (CO-OFDM) communication systems. The system performances are generally measured by the unit of bit error rate (BER). For 64-QAM, the communication length of 850 km can be achieved at the forward error control (FEC) limit.
