Abstract: We propose a threshold-based multiple optical signal selection scheme (TMOS) for free-space optical wavelength division multiplexing systems. With this scheme, we can obtain higher spectral efficiency while reducing the possible complexity of implementation caused by the beam-selection scheme and without a considerable performance loss. To characterize the performance of our scheme, we statistically analyze the operation characteristics under conventional detection conditions (i.e., heterodyne detection and intensity modulation/direct detection techniques) with log-normal turbulence while taking into consideration the impact of pointing error. More specifically, we derive exact closed-form expressions for the outage probability, the average bit error rate, and the average spectral efficiency while adopting an adaptive modulation. Some selected results show that TMOS increases the average spectral efficiency while maintaining a minimum average bit error rate requirement.

Unified Finite Series Approximation of FSO Performance Over Strong Turbulence Combined With Various Pointing Error Conditions
TL;DR: A unified finite series approximation of the composite probability density function is obtained, which embraces generalized pointing error models and leads to new unified formulas for the BER and outage capacity of an FSO link, which account for the two possible detection mechanisms of intensity modulation/direct detection and heterodyne detection.

Adaptive Transmission for Coherent OWC With Multiple Parallel Optical Beams
TL;DR: Analysis and simulation results reveal that activating only suitable optical beams and adapting their transmission parameters significantly improve effective rate (ER) in strict delay constraint and allocating all the power to the strongest optical beam provides near optimal ER at strict delay constrained regimes.
