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 ...

Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...

NHK has been studying a multi-level coded modulation scheme for expanding satellite transmission capacity. It can bring out the transmission performance of multi ...

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 ...

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 ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...
