signal classification based on discrete Fourier transform," in Proc.
For coherent frequency shift keying
modulation is characteristic that, each 1 or 0 bites have equal phase ratio to referential phase.
The transceiver is composed of a direct Gaussian frequency shift keying
(GFSK) modulation transmitter and a dual conversion low IF architecture receiver.
The digital data used to create the modulated Gaussian frequency shift keying
(GFSK) stimulus also is sent to the DSP of the BER measurement channel.
The PHY uses 2-or 4-level Gaussian frequency shift keying
"ZigBee nodes will cost more, decrease battery life, and offer less range than proprietary sub-GHz technologies using frequency shift keying
(FSK)." In most cases, a proprietary point-to-point or star-type network that uses a sub-GHz transceiver will work better and cost less.
Diverse RFID variants use differing modulation formats: On/off keying (OOK), pulse code modulation (PCM), amplitude shift keying (ASK), frequency shift keying
(FSK) and more.
FSK Frequency Shift Keying
A modulation technique that assigns one tone to a 1 and another tone to a 0.
This type of transmission is referred to as frequency shift keying
