Performance Analysis of Quasi-Pulse-Position Modulation Methods,Many modulation methods exist for intensity modulation/direct detection (IM/DD), the earliest of which is on–off keying (OOK) (Barry in Wireless Infrared Communication [M], Springer, New York, 1997); however, it suffers from the influence of external disturbances.

Error Control Based on LDPC Codes,Low-density parity-check (LDPC) codes are linear error-correction codes based on a sparse matrix and were proposed by Gallager in 1962. Their performance can be very close to the Shannon limit.

Research on Polar Codes in Optical Wireless Communication Systems,Using channel polarization, the polar codes considers the mutual information between the input and output when encoding, so that it can use the symmetric capacity of the channel, while ensuring the error-correction performance.

Adaptive Coding Based on Channel Estimation,Light propagation in the atmosphere is subject to attenuation caused by absorption, scattering, and refraction by air; this is especially serious in rainy, snowy, and foggy weather, leading to a sharp increase in the bit-error rate (BER) and even communication interruptions.
