摘要

In this paper, a blind equalization scheme based on the constant norm algorithm (CNA) is proposed for asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) in visible light communication (VLC) system. At the receiver, the CNA can be used to improve system spectral efficiency due to the free of training symbols. The simulation results indicate that for ACO-OFDM signal, the CNA-based blind equalization scheme achieves better mean square error (MSE) performance than that of constant mode algorithm (CMA). Moreover, the CNA-based blind equalization scheme outperforms the CMA scheme in the term of bit error ratio (BER) under same data rate in VLC system.
