Frequency-shift keying (FSK) modulation format

Alternative Names: Frequency-shift keying (FSK) modulation code, Frequency-shift keying (FSK) modulation scheme, Frequency-shift keying (FSK) signaling format.

Description

A \(q\)-ary frequency-shift keying (\(q\)-FSK) encodes one \(q\)-ary digit of information into signals with \(q\) different frequencies. In its standard orthogonal form, each symbol is carried by one of \(q\) approximately orthogonal tones over a fixed symbol interval.
