orthogonal

1. In mathematics, at right angles to or perpendicular to. 2. In telecommunications, describing radio frequency (RF) signals that are independent and mutually exclusive and, therefore, avoid intersymbol interference.Thereby, a receiver can recognize a legitimate signal and reject an unwanted signal or signal element.The concept applies to orthogonal frequency division multiplexing (OFDM), also known as discrete multitone (DMT). See also DMT, interference, RF, signal, and symbol.
