,Leistungsdaten eines Empfängers, the transmitter, has slightly different components, and is at a different temperature, the locally generated symbol clock in the receiver will differ in phase and slightly in frequency from the transmitter‘s clock. Therefore, the receiver must synchronize its symbol clock to the clock in the signal

Demodulation digital modulierter Signale, All current telephone line modems based on the ITU-T V series recommendations for transmission at rates of 2400 bps or more use QAM or include it as an option. These include recommendations V.22 through V.92. This series includes FAX modems. Recommendation V.90 modems normally use PAM in the downst

Deze Zeng,Lin Gu,Shengli Pan,Song Guove full-duplex data transmission over 2-wire circuits. This technique was studied in the early 1980‘s and then widely introduced in commercial products in the mid 1980‘s when the CCITT V.32 recommendation for a 9600 bps modem was approved. A few years later, the V.32bis recommendation for 14.4 kbps

Demodulation digital modulierter Signale,ble, multi-tone wireless, microwave, and satellite systems. It is a popular choice because it uses bandwidth efficiently and linear channel distortions can be corrected by adaptive equalization at the receiver. In addition, QAM fits in nicely with a common combined coding and modulation scheme used
