LED APPARATUS AND METHOD OF CONTROLLING VARIABLE CODE LENGTH IN VISIBLE LIGHT COMMUNICATION BASED ON LIGHT EMITTING DIODE

摘要

[0001] The present invention relates to an apparatus and method for adjusting variable code length in an LED-based visible light wireless communication, and a variable code length adjusting apparatus according to an embodiment, A calculation unit for calculating a spreading diversity gain and an inter-code interference based on the calculated spreading diversity gain and the calculated inter-code interference And a variable code length adjuster for variably controlling the code length in consideration of the comparison result of the magnitude.
