Switching MIMO System with Adaptive OFDM Modulation for Indoor Visible Light Communication by Xinyue Guo, Keer Zhang, Xufa Huang

“…In this paper, we propose and experimentally demonstrate a switching multiple input and multiple output (MIMO) system combining with adaptive orthogonal frequency division multiplexing (OFDM) modulation for high-speed indoor visible light communications. The adaptive OFDM modulation, which is realized by power and bit allocation on OFDM subchannels, is utilized to achieve the maximum channel capacity under a given target bit error rate (BER). …”
