Abstract
Error correction and detection have valuable significance in optical wireless communications systems when the channel is noisy. Convolutional encoding is one of the forward error correction FEC systems that can correct both burst and random errors. One of the most known approaches is OFDM orthogonal frequency division multiplexing for light fidelity of the screen-camera communication system S2C. In this paper, two dimensional direct current optical clipped OFDM for screen to camera communications 2D DCO OFDM S2C and 2D ACO OFDM S2C systems model can be obtained which develops a single screen display, consisting of several cells. The performance of the suggested model was introduced by numerical assessment techniques, as it was checked that within different clipping factors with and without correcting an error, the overall bit error rate BER of \(10^{ - 6}\) signal to noise ratio SNR 17 dB is achieved with convolutional coding. This paper focuses on the performance study of convolutional code FEC by varying clipping factors. The low clipping factor increases the error correction capability. Under the existing IEEE 802.15.7 m standard, the overall results of the S2C OFDM system are being evaluated by comparing them to the 2D OFDM OCC optical camera communication system to illustrate the effectiveness of the proposed system.
