Efficient Direct Detection of M-PAM Sequences with Implicit CSI Acquisition for The FSO System

, 2014
Compared to on-off keying (OOK), M-ary pulse amplitude modulation (M-PAM, M>2) is more spectrally efficient. However, to detect M-PAM signals reliably, the requirement of accurate channel state information is more stringent.

Multi-pulse Fourier codes for bit transmission at the quantum limit

New Journal of Physics
Bit-transmission can be enhanced by the use of quantum detection techniques, realizing a joint-detection receiver (JDR) that is able to decode transmitted signals via a collective operation and achieve the Holevo channel capacity.

Performance Evaluation of Optical Transmission Based on Link Estimation by Using Deep Learning Techniques

IEEE Access
In optical communication systems, the Q-factor is an important performance metric to evaluate the performance of an optical link. In this paper, a deep learning-based eye diagram analyzer is proposed to estimate the Q-factor.
