That is, when the signal 1 is logical '1', the phase of the signal 2 is advanced by S1 and the phase of the signal 2 is unchanged when the signal 1 is logical '0' in the PSK modulation to obtain a digital signal 3 subject to PSK modulation. Then the signal 2' is used to ...
In digital communication systems, the need to map the sequence of the input digital signal waveforms transmitted in the channel, the source output digital sequence, after the signal is mapped to become suitable for the transmission of the channel digital modulated signal, and corresponding to the ...
While traditional wired communication via cables is efficient, wireless long-distance communication, especially radio waves, introduces challenges in maintaining signal integrity due to interference and fading. Digital modulation, including PSK, helps address these issues by leveraging digital ...
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...
