Abstract
In this Letter, we propose a modified hybrid linear and nonlinear post-equalizer to aid pre-convergence of space–time block coding (STBC) decoding in the formulated multiple-input-single-output (MISO) visible light communication (VLC) model. Meanwhile, we present a channel estimation algorithm, as the existing method is suboptimal. Experiments demonstrate that a data rate of 1 Gbit/s is easily achieved in 1.3 m indoor free space transmission with the bit error rate (BER) limited to 3.8 × 10 3 . Correspondingly, the Q factor can be improved to 3.13 dB compared to the pure linear equalizer case.
