Ok kiddo, so Flash-OFDM is like a super fast way for things to get sent over the internet. Imagine you have a toy car and you want to send it to your friend who lives far away. But instead of putting the car in a regular envelope and sending it through snail mail, you put it in a super fast race car and send it through a special highway that goes really really fast!
Flash-OFDM is like that special highway. It sends information (like your toy car) really quickly using a lot of different paths, sort of like many cars going at the same time. This makes sure the information gets to the right place very fast and without any mistakes.
So if you ever need to send something really important like a message to your mom, or maybe even a video call with your grandma, Flash-OFDM can help make sure it gets there in a flash!
