orthogonal - Computer Definition
- In mathematics, at right angles to or perpendicular to.
- 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.
At right angles. The term is used to describe electronic signals that appear at 90 degree angles to each other. It is also widely used to describe conditions that are contradictory, or opposite, rather than in parallel or in sync with each other.
