6. Conclusions

This chapter investigates the performance of the VLC with input-dependent noise. The theoretical expression of the mutual information is derived, which is not in a closed form. Moreover, the closed-form expression of the lower bound on the mutual information is obtained. Furthermore, by employing the OOK, the theoretical expression of the BER for the VLC is derived. Numerical results show that the derived theoretical expressions in this chapter are quite accurate to evaluate the system performance without time-intensive simulations.
