Which digital modulation technique is better?ДЄmplitude modulation methods like ASK/OOK and QAM are far more susceptible to noise so they have a higher BER for a given modulation. What is the similarities between ASK and PSK? QPSK is used for satellite transmission of MPEG2 video, cable modems, videoconferencing, cellular phone systems, and other forms of digital communication over an RF carrier. QPSK allows the signal to carry twice as much information as ordinary PSK using the same bandwidth. What is the difference between PSK and QPSK? The constellation diagram of a QAM signal with two amplitude levels and four phases is shown in Fig. It is possible to obtain higher data rate using QAM. This combined modulation technique is known Quardrature Amplitude Modulation (QAM). This can be improved by combining ASK and PSK. When ASK and PSK are combined what type of modulation is formed? However FSK modulation schemes are more power efficient i,e, offers better BER performance at a given S/N (signal-to-noise ratio). PSK modulation techniques are in general better than FSK modulations in terms of bandwidth requirements or in other words PSK modulation schemes offer better bits/s/hz efficiency. The following plot uses this paper for the FSK analysis, and this page for the BPSK analysis. It is thus difficult to compare them on even terms. Why does PSK is better than ASK and FSK?ДЄs you say in your comment, PSK signals are more bandwidth efficient, but FSK signals have good noise rejection for their data rates. FSK refers to a type of frequency modulation that assigns bit values to discrete frequency levels. ASK refers to a type of amplitude modulation that assigns bit values to discrete amplitude levels. What is the difference between ASK PSK FSK?ДЄmplitude-shift keying (ASK), frequency-shift keying (FSK), and phase-shift keying (PSK) are digital modulation schemes.
