Tóm tắt:

Orthogonal frequency-division multiplexing (OFDM) is a digital multicarrier modulation scheme that is employed in broadband wired and wireless communication as an effective solution with inter-symbol interference caused by a multipath channel. In light fidelity, the OFDM waveform is well-known and frequently implemented; however, the use of such technology with optical camera communication (OCC) is novel. This paper presents the one-dimensional OFDM OCC system. The modulation scheme based on OFDM uses a rolling-shutter effect to transmit data at a high rate. Based on theoretical and experimental validation, we propose a simple system design with various technical details such as system architectures and theoretical analyses of the link budget.
