Experimental Verification and Efficiency Analysis. The results of testing typical channel scenarios for visible light communication systems are presented. Heat maps of threshold parameters and algorithm efficiency are analyzed for the average data transfer rate and the number of switches for all scenarios. Experimental verification, conducted on the developed setup presented in Part 1, demonstrated an increase in the average data transfer rate in the range of 1.88 to 47.62 % relative to the classical threshold algorithm in all studied channel dynamics scenarios. The proposed algorithm reduces the number of modulation order switches relative to the classical threshold method in the range of 7.1 to 81.2 %, depending on the nature of the channel dynamics.
