On the Mutual Information of VLC Systems Employing Color-Shift Keying
IEEE Photonics Technology Letters(2017)
摘要
In visible light communication (VLC), color-shift keying (CSK) is an intensity modulation scheme that transmits data through the variation of color with fixed optical intensity. The mutual information of a CSK modulation scheme is investigated in this letter. An expression for the mutual information of the VLC system is first derived. However, the expression is not in a closed form and its value c...
