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

New modulation schemes don’t come along very often. In fact, it has been years…decades really…. since any new modulation method has been invented. Remember there are only three basic ways a carrier ...

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 ...

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 ...
