Dimming Controllable Hybrid Multilayer OFDM Modulation Method for Indoor Visible Light Communication

Value interval of $η_{p}$	$α$	$β$
$0 \leq η_{p} < η_{l o w}^{}$	0	$\frac{\sum_{l = 1}^{L} \frac{σ}{\sqrt[]{2 π} 2^{l / 2}}}{η (I_{H} - I_{L}) - σ_{s_{n}}}$
$η_{l o w} \leq η_{p} \leq η_{h i g h}$	$\frac{η_{p} (I_{H} - I_{L}) - \sum_{l = 1}^{L} \frac{σ}{β_{0} \sqrt[]{2 π} 2^{l / 2}} - σ_{s_{n}}}{I_{H} - I_{L} - 2 \sum_{l = 1}^{L} \frac{σ}{β_{0} \sqrt[]{2 π} 2^{l / 2}} - 2 σ_{s_{n}}}$	$β_{0}$
$η_{h i g h} < η_{p} \leq 1$	1	$\frac{\sum_{l = 1}^{L} \frac{σ}{\sqrt[]{2 π} 2^{l / 2}}}{(1 - η) (I_{H} - I_{L}) + σ_{s_{n}}}$
