Hierarchical modulation, also known as layered modulation, is a technique that embeds multiple data streams of differing priority within a single carrier waveform. By allocating distinct amplitude and ...

As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many applications, such as electronic warfare, wireless communications and modern radar systems. Initially, ASK ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...
