WebJul 1, 2024 · Optical orthogonal frequency division multiplexing (OFDM) has been extensively used in visible light communication (VLC) systems to improve the efficiency of bandwidth and throughput [1]. In the VLC systems, the optical signal is real and positive [2]. WebOne of the most potential modulation techniques for VLC is orthogonal frequency division multiplexing (OFDM), but the challenge is the output signal must be real and positive. Therefore OFDM needs to be modified, by adding DC-bias called direct current-biased optical OFDM (DCO-OFDM) or by signal clipping called asymmetrically clipped optical ...

WebSynchronization at the receiver of a practical orthogonal frequency division multiplexing (OFDM) system design is one of the most crucial data detection stages that must be performed accurately in order to avoid system performance degradation due to symbol timing and carrier frequency offset [ 1 ]. The performance of any communication system can be measured in terms of its power efficiency and bandwidth efficiency. The power efficiency describes the ability of communication system to preserve bit error rate (BER) of the transmitted signal at low power levels. Bandwidth efficiency reflects how efficiently the allocated bandwidth is used and is defined as the throughput data rate per hertz in a given bandwidth. If the large number of subcarriers are used, the bandwidth efficie…
