This paper delves into the key modulation techniques and demonstrates their simulation using LabVIEW, providing valuable ...

Just like it says on the tin, it’s phase shift keying, and a proper implementation uses a phase detection circuit or something similar. [Craig] thought it would be fun to build an analog BPSK31 ...

Abstract: This paper presents a chaotic oscillator-based binary phase-shift keying (CO-BPSK) modulation scheme, exploiting the chaotic dynamics to achieve carrier phase inversion. A basic analytical ...

In 4FSK, the bit rate is two times the baud rate. Phase-shift keying (PSK) is another popular example. When employing binary PSK, each symbol represents a 0 or 1 (see the table). A binary 0 equals ...

These downlinks contain satellite position data, orbital elements, uplink/downlink channel info, and encrypted user messages. The STX downlinks are modulated using Symmetrical Differential Phase Shift ...

Recently [7], it was experimentally demonstrated a FWM regenerator that exhibited significant amplitude and phase noise suppression for returning-to-zero differential shift keying (RZ-DPSK) signals. A ...

Quantum state discrimination is made easier: A practical strategy to beat the standard quantum limit at low input power and without adaptive feedback is demonstrated.

Quadrature phase-shift keying is now the mainstream method used for modulation in cable modems, satellites, and numerous other wireless communication schemes. The signature constellation pattern of ...
