Another modulation scheme similar to FM is phase modulation. Within the genre of phase modulation, there are many subsets. These schemes lend themselves well to digital uses, and are seen frequently ...

Offset Quadrature Amplitude Modulation (OQAM) stands as one such innovation, in which the in-phase and quadrature components are staggered in time.

Also known as IQ modulation, the signaling has become a staple in wireless digital communications. It's based on modulating signals that are 90 degrees apart in phase.

This article details a quadrature amplitude modulation (QAM)-based multi-bit per baud modulation scheme that makes it possible to deliver 10GE connections over UTP cables by solving the design ...

Traditional single-carrier (SC) modulation-based wireless systems, such as quadrature amplitude modulation (QAM), shaped-offset quadrature phase-shift keying (SOQPSK), and the like, have shown a ...

Finally, AM is still with us in QAM form, the combination of phase and amplitude modulation. Most OFDM channels use one form of QAM to get the higher data rates they can deliver.

Keysight Technologies, Inc. (NYSE: KEYS) gained validations for the industry’s first 5G NR FR1 1024-QAM demodulation test cases based on the 3GPP TS 3 ...

Offset Quadrature Amplitude Modulation (OQAM): A modulation technique that staggers the in-phase and quadrature components in time, reducing interference and improving spectral efficiency.
