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 ...

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 ...

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.

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 ...

Despite these disadvantages, QAM is the modulation of choice in wireless LANs, cell phones, and other wireless systems especially those using OFDM.

However, before implementing a VDSL-based connection, two decisions have to be made. The first is which transport protocol to use, Ethernet or asynchronous transfer mode (ATM). The second is which of ...

The startup will demonstrate in a private suite at the Consumer Electronics Show an FPGA board using its technology to deliver a 10dB signaling advantage compared to QAM4096, the most powerful version ...
