Two-dimensions asymmetrically clipped optical orthogonal frequency division multiplexing for screen to a camera communications system

Orthogonal frequency division multiplexing (OFDM) of the optical communication system is a known approach for light fidelity and the screen-to-a-camera (S2C) communication system is an innovative implementation for optical camera communication (OCC). In This paper, two dimensional (2D) asymmetrically clipping optical (ACO) OFDM for the S2C model can be obtained which develops a single screen display, consisting of several cells, for a data rate of up to 100 kb/s. This paper contains an innovative system design focused on validation of implementation and theoretical study. The source distribution of the ACO OFDM system has been implemented using LAB VIEW software. The performance of the suggested model was verified through numerical assessment techniques, as it was checked that within the transmission distance of 4.5 m and the field of view of 30 degrees overall bit error rate (BER) of 10(-6) and signal to noise ratio (SNR) 18 dB is achieved. 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 system to illustrate the efficiency of the proposed scheme.
