Who is Orthogonal Frequency Division Multiplexing?

Orthogonal Frequency Division Multiplexing is like having multiple friends send you messages at the same time using different colored pencils so you can read them all clearly.

Imagine you're playing a game where your friend sends you notes through a tube, but sometimes the paper gets crumpled and hard to read. If only one friend sends notes at a time, it's easy, but if many friends send notes all at once, they might mix up and get confusing.

That’s where Orthogonal Frequency Division Multiplexing comes in. It acts like a smart organizer who gives each friend a unique colored pencil. Even though everyone is sending notes through the same tube, you can still tell which note belongs to whom because of their colors, just like how different frequencies work together so all messages stay clear and separate.

Think of each color as a frequency, and every friend using a unique one sends their message without getting tangled up. This way, even if the paper gets crumpled, you can still read each note clearly because they are using different colors, or frequencies, to stand out from each other.
