The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

While delivering 10 Gigabit Ethernet (10GE) transport over optical connections is growing in metro and core networks, adoption of optical-based 10GE solutions has been slowed in the enterprise data ...

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into channels owned and ...

Unless you design EDGE or 3G/UMTS cell phone handsets, you may not have heard of polar modulation. As you know, there are only a few basic types of modulation, but they have been used in a variety of ...

As our society’s hunger for data grows—not only more data, but more data delivered faster—older modulation schemes based on NRZ-type encoding grow increasingly inadequate. We need to get data from ...
