Abstract: Quadrature amplitude modulation (QAM) is widely used in many digital communication systems such as high speed modems. Increasing the data rate by using larger constellations has brought a ...

Fundamental continuous and discrete-time signals and their implementations using Matrix laboratory. Concepts include CTS, DTS, Amplitude modulation, Amplitude demodulation, Double sideband suppressed ...

Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently. This effectively aligns with the growing ...

Researchers from Science Tokyo, Japan have developed three design techniques to substantially enhance wireless transmitter performance, boost power efficiency and elevate data rates concurrently.

The proposed CORDIC-less digital polar transmitter demonstrates superior power added efficiency (PAE) and system efficiency (SE) for similar modulation signals. It also supports wider bandwidths, ...

Cyanobacteria use an AM radio-like mechanism to regulate their genes, with the cell division cycle acting as a “carrier wave” and their circadian clock modulating the pulse strength to integrate ...
