Abstract

In this work, a designed fractionally spaced equalizer (FSE) is introduced to the visible light communication (VLC) system using multi-carrierless amplitude phase (m-CAP) modulation to suppress the high-frequency fading. The bit error ratio (BER) performance of the VLC system with FSE at different transmission rates, signal noise ratio (SNR) condition and QAM order is investigated and compared with that with SSE. The simulation results show the performance of m-CAPVLC system can be improved by using FSE. As a result, when T/2 FSE and T/4-FSE are used, 73Mb/s and 90Mb/s transmission rate can be obtained under the condition of 18dB SNR, respectively.
