What does DPSK mean in AMATEUR RADIO
DPSK stands for Differential Phase-Shift Keying. It is a method of digital modulation which uses the abrupt changes in signal phase instead of amplitude or frequency, to represent the data being transmitted. It is one of the higher level forms of frequency shift keying (FSK).

Essential Questions and Answers on Differential Phase-Shift Keying in "SCIENCE»AMRADIO"
What is Differential Phase-Shift Keying?
Differential Phase-Shift Keying is a type of digital modulation which uses sudden shifts in signal phase instead of changes in amplitude or frequency, to represent the data being transmitted.
What advantages does differential phase-shift keying have over other types of digital modulation?
Differential phase-shift keying provides improved performance over other types of digital modulations since it does not require very accurate frequencies. Additionally, it is less sensitive to timing and noise errors than other forms of FSK modulation.
What type of radio systems use differential phase-shift keying?
Many wireless communication systems, including WiMAX and third generation (3G) cellular systems, employ differential phase-shift keying as their primary form of digital communication.
How does differential phase-shift keying work?
In differential phase-shift keying, a pulsed RF carrier wave with two distinct phases is sent through an oscillator. As each successive bit arrives at the oscillator, the phase from one symbol to another is compared and evaluated — this comparison allows for each bit to be determined without needing any prior reference points. The sudden change in signal from one bit to another creates a detectable difference that can be detected by receivers on the other end.
Can differential phase-shift keying be used for encoding analog signals?
Yes, although it has typically been used as a form of digital modulation, DPSK can also be employed to encode analog signals too. This process requires more complex coding schemes than are employed with regular digital modulations, however noise resilience can still be maintained with these schemes even when analog signals are involved.
Final Words:
Differential Phase Shift Keying offers an effective way to send data wirelessly over long distances and with greater accuracy than traditional methods can provide. With its improved immunity against noise disturbances and lesser need for exact timing accuracy, DPSK remains one of the more popular choices for modern radio communication systems today.
