Quadrature amplitude modulation (QAM) is the name of a family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier waves, using the amplitude-shift keying (ASK) digital modulation. QAM restores the balance by placing two independent double sideband suppressed carrier signals in the same spectrum as one ordinary double sideband supressed carrier signal. Analogue and digital QAM. Quadrature amplitude modulation, QAM may exist in what may be termed either analogue or digital formats What is QAM? Quadrature amplitude modulation (QAM) is the name of a family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information.QAM is both an analog and a digital modulation scheme. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier. Quadrature-amplitude-modulation (QAM) codes are used in microwave digital radio for transmission with enhanced spectral efficiency over limited channel bandwidths. An outline diagram of a transmitter with such modulation is shown in Fig. 17.3, while Fig. 17.4 outlines the receiver segments What is QAM (Quadrature Amplitude Modulation)? QAM (Quadrature Amplitude Modulation) is defined as the modulation technique which is the combination of phase and amplitude modulation of a carrier wave into a single channel. In other words, QAM transmits information by changing both the amplitude and phase of a carrier wave, thereby doubling the effective bandwidth

Quadrature Amplitude Modulation - an overview

English: Quadrature amplitude modulation (QAM) is a modulation scheme which conveys data by changing (modulating) the amplitude of two carrier waves independently.These two waves, usually sinusoids, are out of phase with each other by 90° and are thus called quadrature carriers—hence the name of the scheme Use the de2bi function to convert the data symbols from the QAM demodulator, dataSymbolsOut, into a binary matrix, dataOutMatrix, with dimensions N sym -by- N bits / sym. In the matrix, N sym is the total number of QAM symbols, and N bits / sym is the number of bits per symbol. For 16-QAM, N bits / sym = 4 Looking for the definition of QAM?

The basic way in which a QAM signal can be generated is to generate two signals that are 90° out of phase with each other and then sum them. This will generate a signal that is the sum of both waves, which has a certain amplitude resulting.
