Examples

Analog QAM suffers from the same problem as Single-sideband modulation : the exact phase of the carrier is required for correct demodulation at the receiver. Source: Internet

Bit-loading (bits per QAM constellation) on an ADSL line Communication systems designed to achieve very high levels of spectral efficiency usually employ very dense QAM constellations. Source: Internet

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. Source: Internet

For example, hierarchical QAM is used in DVB, where the constellation points are grouped into a high-priority QPSK stream and a low-priority 16-QAM stream. Source: Internet

Expressions for the symbol-error rate of rectangular QAM are not hard to derive but yield rather unpleasant expressions. Source: Internet
