Multicarrier modulation (MCM) technique permits the parallel transmission of data along a number of sub-channels to increase capacity and/or combat channel impairments. This technique is also termed subcarrier modulation and can be configured such that the sub-channels are orthogonal with the nomenclature orthogonal frequency division multiplexing (OFDM). This talk will provide a synopsis of the MCM technique in optical wireless communication systems covering its application in attaining gigabit per second data rate in visible light communication, combating channel adversities (including atmospheric turbulence in free-space optical communications) as well as its implementation challenges and recent advances.
