    Delivery of 12QAM Single Carrier Signal in a MIMO Radio-Over-Fiber System at 60 GHz

    Delivery of 12QAM Single Carrier Signal in a MIMO Radio-Over-Fiber System at 60 GHz af Miao Kong, Wen Zhou

    Udgivet 2017-01-01

    As we know, the gap between 8-QAM and 16-QAM can be filled smoothly by introducing 12-QAM. In this paper, we experimentally demonstrated a reliable 10 Gbaud-rate transmission of polarization multiplexed 12-QAM single carrier signal in a MIMO radio-over-fiber system with 20-km SMF-28 wire...

    Demonstration of 4 × 100 Gbit/s PAM-4 Transmission Over 40 km in an IM/DD System Based on Narrow Band DMLs

    Demonstration of 4 × 100 Gbit/s PAM-4 Transmission Over 40 km in an IM/DD System Based on Narrow Band DMLs af Kaihui Wang, Mingming Zhao, Miao Kong, Jianjun Yu

    Udgivet 2020-01-01

    We demonstrate a four-lane wavelength division multiplexing (WDM) intensity modulation and direct detection (IM/DD) system at O-band. The 3-dB bandwidth of directly modulated lasers (DMLs) in this experiment is only 15 GHz. To support 100-Gbit/s/lane PAM-4...

    Performance Comparison of PS Star-16QAM and PS Square-Shaped 16QAM (Square-16QAM)

    Performance Comparison of PS Star-16QAM and PS Square-Shaped 16QAM (Square-16QAM) af Bo Liu, Ying Zhang, Kaihui Wang, Miao Kong, Lijia Zhang, Qi Zhang, Qinghua Tian, Xiangjun Xin

    Udgivet 2017-01-01

    We investigate and compare the performance of star-shaped 16-ary quadrature amplitude modulation (Star-16QAM) and square-shaped 16QAM (Square-16QAM) in the probabilistic shaping (PS) and uniform schemes with coherent detection. With the help of PS technology, the bit error ratio (BER) improvement ac...

    PAM-8 IM/DD Transmission Based on Modified Lookup Table Nonlinear Predistortion

    PAM-8 IM/DD Transmission Based on Modified Lookup Table Nonlinear Predistortion af Jiao Zhang, Pengqi Gou, Miao Kong, Kaibo Fang, Jiangnan Xiao, Qi Zhang, Xiangjun Xin, Jianjun Yu

    Udgivet 2018-01-01

    In this paper, a modified lookup table (LUT) nonlinear predistortion method is proposed. With the modified LUT method, the number of patterns and the computational complexity can be reduced by half with a similar system performance comparing with normal LUT. We experimentally demonstrate an 8-ary pu...

    LDPC-Coded Generalized Frequency Division Multiplexing for Intensity-Modulated Direct-Detection Optical Systems

    LDPC-Coded Generalized Frequency Division Multiplexing for Intensity-Modulated Direct-Detection Optical Systems af Dong Guo, Wei Zhang, Feng Tian, Jianyang Shi, Kaihui Wang, Miao Kong, Junwen Zhang, Kai Lv, Deng'ao Li, Xiaolong Pan, Xiangjun Xin

    Udgivet 2019-01-01

    In this paper, a low-density parity check (LDPC) coded GFDM with high-level modulation scheme is proposed for more flexible and advanced multicarrier modulation in intensity-modulated/direct-detection (IM/DD) optical systems. Then, we experimentally demonstrate an LDPC-coded GF...
