In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

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 ...

Due to efficiency, quality, and cost, digital communications systems play a major role in telecommunications, especially wireless services. With most digital modulation schemes represented as in-phase ...

Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...

Signal modulation is one of the most basic and important concepts in the RF industry. It consists of using the variation of one or more parameters of a carrier signal to transmit information, ...

We all love our wireless devices. We want more features, higher data rates, and improved range. These demands, in turn, require advanced digital protocols. Meanwhile, the number of signal sources is ...
