Research Paper on OFDM

OFDM (Orthogonal frequency-division multiplexing) is a method of coding digital signals by orthogonal frequency division as multiple subcarriers. This technique allows to fight against frequency-selective channels allowing equalization of low complexity. These channels are particularly apparent in the presence of multipath and are particularly disadvantageous when the transmission rate is high. This technique is widely adopted in most applications with very high speed.

There exist several variants of OFDM. DMT (Discrete Multi Tone) refers to a system for transmitting OFDM baseband. The COFDM (Coded Orthogonal Frequency Division Multiplexing) introduces error correcting code. WCP-OFDM (Cyclic Prefix Weighted Orthogonal Frequency-Division Multiplexing) includes the addition of a cyclic prefix and the weighting of the output signal of the transmitter to adapt the mobile multipath channels.
