Frequency shift keying radar
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is encoded on a carrier signal by periodically shifting the frequency of the carrier between several discrete frequencies. The technology is used for communication systems such as telemetry, weather balloon … See more Reference implementations of FSK modems exist and are documented in detail. The demodulation of a binary FSK signal can be done using the Goertzel algorithm very efficiently, even on low-power … See more Multiple frequency-shift keying Continuous-phase frequency-shift keying In principle FSK can be implemented by using completely independent free-running oscillators, and … See more Frequency-shift keying (FSK) is commonly used over telephone lines for caller ID (displaying callers' numbers) and remote metering applications. … See more • dFSK: Distributed Frequency Shift Keying Modulation in Dense Sensor Networks • M Nasseri, J Kim, M Alam - Proceedings of the 17th Communications & Networking, 2014, Unified metric calculation of sampling-based turbo-coded noncoherent MFSK for mobile channel See more In 1910, Reginald Fessenden invented a two-tone method of transmitting Morse code.

MFSK is a form of M-ary orthogonal modulation, where each symbol consists of one element from an alphabet of orthogonal waveforms. M, the size of the alphabet, is usually a power of two so that each symbol represents log2M bits.

Webwww.ncbi.nlm.nih.gov Webspeed. The keying speed in “bauds” is equal to the inverse o f the element length in seconds. For example, an element length of 20 milliseconds (.02 seconds) is equivalent to a 50 -baud keying speed. Frequency measurements of the FSK signal are usually stated in terms of “shift” and center frequency.
