Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

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 ...

Terahertz modulation in metamaterial systems harnesses engineered resonant structures to dynamically control the amplitude, phase and polarization of electromagnetic waves in the 0.1–10 THz band. By ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

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

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...

Researchers have built a miniaturized microcomb-driven terahertz wireless communication system that's 90 times smaller than ...
