What is QAM streaming?
QAM (quadrature amplitude modulation) is a method of combining two amplitude modulation (AM) signals into a single channel. This approach helps double its effective bandwidth. QAM is also used with pulse AM (PAM) in digital systems, like wireless applications.
What is the significance of QAM?
QAM is used extensively as a modulation scheme for digital telecommunication systems, such as in 802.11 Wi-Fi standards. Arbitrarily high spectral efficiencies can be achieved with QAM by setting a suitable constellation size, limited only by the noise level and linearity of the communications channel.
What is the disadvantage of QAM?
Disadvantages are, QAM modulation process is more prehensile to the noise. Due to this QAM, receiver is more difficult compare to receivers of other modulation types. To transmit QAM signal linear amplifier is needed which consumes more power.
What are the applications of QAM modulation?
Applications of the QAM Method
In radio communication systems and data delivery applications, QAM is widely used. Most of the high-speed data, video-on-demand, HD television, Internet Protocol cable television, and wireless cellular and digital systems are run by QAM.
