摘要/Abstract

摘要： 为实现短距离光传输系统在低成本下提升速率的目标，提出了一种基于强度调制/直接检测的偏振复用4阶脉冲幅度调制光纤传输系统. 该系统结构简单，利用高效的数字信号处理算法，包括偏振态估计、混合偏振拍打噪声消除、基于最小均方误差算法的自适应多入多出技术滤波，可实现稳定可靠的均衡解复用. 在Matlab和VPI软件联合仿真平台上，对224 Gbit/s PDM-PAM4系统进行了仿真验证.

Abstract: In order to satisfy the demand of short reach optical communication system with low cost for higher rate, an optical fiber transmission system was proposed based on intensity modulation and direct detection(IM/DD) polarization division multiplexing 4 order pulse amplitude modulation(PDM-PAM4). The system's structure is simple. By utilizing the effective digital signal processing(DSP) algorithm, including the station of polarization(SOP) estimation, mixed polarization beat interference(MPBI) elimination and adaptive multiple-input multiple-output(MIMO) filter based on least mean square(LMS) algorithm, its stablity and reliablity can be realized. Finally in the Matlab and VPI software joint simulation platform, a 224 Gbit/s PDM-PAM4 system was simulated and analyzed in detail.

Key words: polarization division multiplexing, intensity modulation and direct detection, 4 order pulse amplitude modulation, short reach optical communication
