basic concept of OFDM is quite simple [4]–[7]. Data is transmitted in parallel on a number of different frequencies, and as a result the symbol period is much longer than for a serial system with the same total data rate. Because the symbol perio

OFDM as a modulation technology, it transmit over both wireless and optical channel, and it distribute the data over a large number of subcarrier can be overlapping. It achieved RF signal for the long haul transmission using RoF system.
