This paper suggests employing channel encoders techniques to develop the attainment of the Flip-OFDM system. Reed Solomon (RS) and convolutional coders (CC) are used as channel coding techniques. Simulation works are carried out in AWGN channel and flat fading optical LOS channel surroundings to compare the performance of Non-Encoded VLC-OFDM, Non-Encoded Flip-OFDM, RS-Coded Flip-OFDM and 1/2 rate CC Coded Flip-OFDM systems on bit error rate (BER) achievement benchmark. From the acquired numerical outcomes, it is observed that especially the 1/2 CC Coded Flip-OFDM method is better than other methods. In addition, it is understood from the results that with the 1/2 CC Coded Flip-OFDM method, approximately 18 dB SNR development is achieved for the 1E-3 BER value against the Un-Coded VLC-OFDM method. © 2021 IEEE.
