In this article, it is recommended to use the M-Level Color Switching (M-CSK) modulation without vibration problems in the Flip-OFDM wave form, which is an efficient single-pole version of OFDM for optical wireless communication systems. The performance of the recommended scheme is compared with the M-QAM modular Flip-OFDM and M-CSK modular VLC OFDM methods based on the criteria of bit-feat ratio (BER) and top average power ratio (PAPR). BER performance was also analyzed using the first uncoded recommended scheme, then two channel coding techniques, i.e. Reed-Solomon (RS) channel coder and Evolutionary Codes (CC) using two channels, i.e. AWGN and optical LOS channel. All channel coding techniques are performed using QAM modulation. The simulation results show that the recommended M-CSK Flip-OFDM method has achieved good performance at high SNR values for both the AWGN channel and the optical LOS channel, and also improved the BER performance by applying RS and CC.
