Guard Interval
In telecommunications, guard intervals are used to ensure that distinct transmissions do not interfere with one another. These transmissions may belong to different users (as in TDMA) or to the same user (as in OFDM).
The purpose of the guard interval is to introduce immunity to propagation delays, echoes and reflections, to which digital data is normally very sensitive.

Famous quotes containing the words guard and/or interval:
“Let us guard against saying that there are laws in nature. There are merely necessities: there is no one who commands, no one who obeys, no one who transgresses. Once you understand that there are no purposes, then you also understand that nothing is accidental: for it is only in a world of purposes that the word “accident” makes sense.”
—Friedrich Nietzsche (1844–1900)
“The yearning for an afterlife is the opposite of selfish: it is love and praise for the world that we are privileged, in this complex interval of light, to witness and experience.”
—John Updike (b. 1932)
