An achievable information rate of 10.23 Gbps over a 1.2m indoor free space transmission with normalized generalized mutual information above 0.92 is reported. This is achieved due to the use of probabilistic shaping bit loading scheme to maximize the spectral efficiency. ? 2020 IEEE.Beryllium compounds; Digital signal processing; Gallium nitride; III-V semiconductors; Information theory; Light; 10 Gbps; Achievable information rate; Bit loading; Free-space transmission; GaN laser diodes; Generalized mutual information; High data rate; Spectral efficiencies; Visible light communicationBit loading; Laser diode; Probabilistic Shaping; Visible Light CommunicationBeryllium compounds; Digital signal processing; Gallium nitride; III-V semiconductors; Information theory; Light; 10 Gbps; Achievable information rate; Bit loading; Free-space transmission; GaN laser diodes; Generalized mutual information; High data rate; Spectral efficiencies; Visible light communicationconference paper10.1109/CSNDSP49049.2020.92494822-s2.0-85097654565
