S-band single-longitudinal-mode erbium-doped fiber ring laser with ultra-narrow linewidth, ultra-high OSNR, high stability and low RIN
Zhengkang Wang, Jianming Shang, Siqiao Li +3
A high-performance S-band single-longitudinal-mode (SLM) erbium-doped fiber (EDF) ring cavity laser based on a depressed cladding EDF is investigated and experimentally demonstrate…
All-Polarization Maintaining Single-Longitudinal-Mode Fiber Laser with Ultra-High OSNR, Sub-kHz Linewidth and Extremely High Stability
Zhengkang Wang, Jianming Shang, Siqiao Li +3
An all-polarization maintaining (PM) single-longitudinal-mode (SLM) erbium-doped fiber laser (EDFL) with ultra-high optical signal-to-noise ratio (OSNR), ultra-narrow linewidth and…
Modified QPSK Partition Algorithm Based on MAP Estimation for Probabilistically-Shaped 16-QAM
Jin Hu, Zhongliang Sun, Xuekai Xu +4
Probabilistic shaping (PS) is investigated as a potential technique to approach the Shannon limit. However, it has been proved that conventional carrier phase recovery (CPR) algori…
Fixed-State Log-MAP Detection for Intensity-Modulation and Direct-Detection Optical Systems over Dispersion-Uncompensated Links
Shuangyue Liu, Ji Zhou, Haide Wang +3
In this paper, an optimized detection based on log-maximum a posteriori estimation with the fixed number of surviving states (fixed-state Log-MAP) is proposed to cooperate with equ…
Sphere Decoder with Box Optimization for FTN Non-orthogonal FDM System
Mengqi Guo, Ji Zhou, Yueming Lu +1
In 1975, the pioneering work of J. E. Mazo showed the potential faster-than-Nyquist (FTN) gain of single-carrier binary signal. If the inter-symbol interference is eliminated by an…
An Improved Diversity Combining Receiver for Layered ACO-FOFDM in IM/DD Systems
Mengqi Guo, Ji Zhou, Xizi Tang +5
In this paper, an improved receiver based on diversity combining is proposed to improve the bit error rate (BER) performance of layered asymmetrically clipped optical fast orthogon…
Faster-than-Nyquist Non-Orthogonal Frequency-Division Multiplexing for Visible Light Communications
Ji Zhou, Yaojun Qiao, Tiantian Zhang +6
In this paper, we propose a faster-than-Nyquist (FTN) non-orthogonal frequency-division multiplexing (NOFDM) scheme for visible light communications (VLC) where the multiplexing/de…
Capacity limit for faster-than-Nyquist non-orthogonal frequency-division multiplexing signaling
Ji Zhou, Yaojun Qiao, Zhanyu Yang +2
Faster-than-Nyquist (FTN) signal achieves higher spectral efficiency and capacity compared to Nyquist signal due to its smaller pulse interval or narrower subcarrier spacing. Shann…
