Orthogonal Frequency Division Multiplexing over Multimode Optical Fibers
نویسندگان
چکیده
Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation technique which is already widely employed in both wireless communication systems (WLAN, DVB-T, WiMAX) as well as wireline systems (ADSL, VDSL, PLC). Due to highly increasing speeds and lower costs of electronics, OFDM has recently also gained much interest in optical communication systems. In this paper, we will discuss the use of OFDM to counter the problem of multipath propagation in mutimode fibers (MMF) and the simultaneous use of spectrally efficient modulation schemes such as quadrature amplitude modulation (QAM) to increase the capacity of MMF transmission links.
