What are the main strengths of OFDM?
Immunity to selective fading: One of the main advantages of OFDM is that is more resistant to frequency selective fading than single carrier systems because it divides the overall channel into multiple narrowband signals that are affected individually as flat fading sub-channels.
Why do orthogonal signal not interfere?
At orthogonal frequencies, the individual peaks of subcarriers all line up with the nulls of the other subcarriers. This overlap of spectral energy does not interfere with the system's ability to recover the original signal.
What are the differences between FDM and OFDM *?
In FDM, Bandwidth (B) is committed to the different sources. Orthogonal Frequency Division Multiplexing (OFDM): It is also the multiplexing technique which is used in analog system. In OFDM, Guard band is not required and the spectral efficiency of OFDM is high which oppose to the FDM.
What is orthogonal in wireless communication?
Orthogonal frequency-division multiplexing is a method of data transmission where a single information stream is split among several closely spaced narrowband subchannel frequencies instead of a single Wideband channel frequency.
