BER performance study for optical OFDM of optical camera communication

In this article, different forms of optical orthogonal frequency division multiplexing (OFDM) were observed which suitable for camera communication (OCC) systems. This research aims to establish the bit error rate (BER) versus signal-to-noise ratio (SNR) OCC system. will focus on systems and design that produces noise clipping but gain SNR as a whole if an optimum factor is chosen. The BER analysis was investigated factors 0.7, 1.4, 2.6. performance asymmetrically clipped OFDM (ACO-OFDM) also compared with direct current (DCO-OFDM) show effectiveness proposed approach. ACO-OFDM considered be better due lower loading, DCO-OFDM efficient higher values. because DC bias used inefficient in terms capacity, while only half subcarriers transmit information. Moreover, two-dimensional half-subcarriers mapping rule would introduce its unused 2D subcarriers, although further data can provided by rule.
