Orthogonal Time Frequency and Space
Orthogonal Time Frequency and Space (OTFS) is a way of sending signals from one place to another. It helps to separate different signals from each other, so that they do not interrupt each other and do not interfere with each other.
Think of a radio station that can play multiple songs at the same time, but it's difficult for you to listen to all the songs at once because the songs mix in with each other. OTFS makes it easier to send many signals at once without them interfering with each other. It does this by separating the signals in both time and frequency (like saying how often it is sent) and space (like saying where it should go). OTFS makes sure that the signals don't get mixed together by giving them a clear path to travel in.
