FDPSK Meaning and
Definition
-
Frequency-Shift Differential Phase-Shift Keying (FDPSK) is a digital modulation scheme used in telecommunications and wireless communication systems to encode and transmit data over a carrier wave. It is a variant of phase-shift keying (PSK) modulation schemes that offers improved performance in terms of spectral efficiency and robustness.
In FDPSK, the carrier wave's frequency is shifted in discrete steps, and the phase of the carrier wave is differentially modulated according to the input data. This modulation technique helps to reduce sudden phase changes and improve the signal-to-noise ratio, thereby increasing the transmission reliability. By using differential encoding, FDPSK can mitigate the effects of fading, multipath propagation, and channel distortion.
The transmitted signal in FDPSK is generated by continuously monitoring the phase difference between adjacent symbols. This phase difference is then modulated using a predetermined phase shift in relation to the previous symbol, allowing for the transmission of multiple bits per symbol. FDPSK is commonly used in wireless applications where robustness to phase noise and low power consumption are essential, such as in satellite communication systems, wireless local area networks (WLANs), and wireless sensor networks (WSNs).
In conclusion, FDPSK is a digital modulation scheme that uses frequency-shifting and differential phase-shifting techniques to encode and transmit data, providing improved spectral efficiency, robustness, and resistance to channel impairments in wireless communication systems.
