A Novel Pilot Pattern Channel Estimation Scheme With MMSE-DFT For MIMO-OFDM VLC System

A novel pilot pattern channel estimation scheme with MMSE-DFT is proposed for 2×2 MIMO-OFDM VLC system. The simulation results show that a 3dB promotion of SNR is obtained compared to STBC based scheme for 32-QAM format with BER below FEC threshold of 3.8× 10<sup>−3</sup>.
