Phase-shift keying (PSK) happens when data is transmitted by changing wave frequency . A finite number of changes are used in PSK, making the frequency changes trackable and understandable for those receiving the data. Where one method of data transmissi
突发模式无前导字The application of burst-mode communication becomes even popular. The demodulator with pre-amble may reduce data transmission efficiency of the system. A scheme of full-digital burst-mode demod-ulator without preamble suitable for multiple symbol rates is proposed. FIFO operation and...
In this experiment, we studied the process of phase shift keying (PSK) modulation and demodulation. PSK is a digital modulation technique that conveys data by changing the phase of the carrier wave. It is widely used in communication systems due to its efficiency and robustness. The purpose of...
According to Shannon's theorem, PSK demonstrates the trade-off between data rate and signal-to-noise ratio (SNR). In challenging communication environments like shortwave bands, PSK's resilience to noise makes it a practical choice despite its complexity compared to simpler methods. It ...

➨PSK modulation is sensitive to phase noise, which can arise from various sources, including imperfections in the transmitter or distortions in the communication channel. This sensitivity can affect the quality of the demodulated signal. ➨PSK modulation may exhibit reduced performance in non-idea...
2.1 Protocol stack Below is a list of the protocol layers and functions embedded in the ST7580: Physical (PHY) layer: hosted in the PHY processor, implements two different modulation schemes for communication through power line: a B-FSK modulation up to 9.6 kbps and a multi-mode PSK ...
Zero BER data recoveryA Coherent phase-shift-keyed (CPSK) wireless data communication circuit, based on differential signaling, is simulated for error-free data recovery. The simulated circuit is tested and the results are reported, indicating error-free data recovery. In these simulation tests, ...
The AP also generates a Group Transient Key (GTK) to protect all broadcast and multicast communication. Because every station on the WLAN needs that same GTK to decrypt broadcast/multicast frames, the AP sends the current GTK in message #3 of the handshake. To prevent eavesdropping, the GTK ...
