Reduced CSPR requirement of the single-photodiode receiver for the free-space optical transmission
A weighted K-means algorithm is introduced to improve the performance of the FSO-based KK receiver under lower CSPR and large atmospheric turbulence, the numerical simulation results show that by using the weighted K-means algorithm, a 1dB CSPR reduction is obtained when the FSO link length is extended to 3000m, compared to the conventional hard-decision scheme.
