Whether you know it or not, the most popular modulation scheme in use in the wireless world today is QAM or quadrature amplitude modulation. It is a combination of both amplitude and phase ...

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.

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): A modulation technique that staggers the in-phase and quadrature components in time, reducing interference and improving spectral efficiency.

The new technology is “WAM” (WAve Modulation) that the company says will challenge the 40-year dominance of QAM (Quadrature Amplitude Modulation) as the modulation methodology of choice for advanced ...

(b) Using both I and Q arm for modulation, resulting in a bandwidth requirement of Hz— called QAM (quadrature amplitude modulation). Based on knowledge of symbol duration and bandwidth requirement, ...

Surprisingly, the availability of the 256 QAM modulation scheme in the macro network was on par with the availability of 64 QAM in an HSPA+ network, based on a comparison of these most recent ...

Modern Modulation Techniques Jul 1, 2014 9:00 AM, Jeremy Ruck, PE Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding ...

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 ...

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