Orthogonal Frequency Division Multiplexing (OFDM)
-System which encodes two bits per symbol
-Each symbol has a real part, and imaginary part
-Real and Imaginary axes
-Each Quadrant assigned a particular symbol
General model of an OFDM system
Noise is picked up during data transmission
How does OFDM cope with noise?
How much noise can the system handle?
Faster computation of FFT / IFFT due to
parallel multiply accumulates.
Smaller noise margin due to smaller amount
of data being transmitted per channel.
