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 ...

Index modulation techniques represent a paradigm shift in wireless communications by embedding information not only in conventional amplitude and phase symbols but also in the selection of ...

Power-density improvements are an increasingly elusive goal as designers exhaust the easiest or most obvious solutions. One direction that’s now being explored more thoroughly is advanced modulation ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

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 ...

As the demand for high-speed, energy-efficient optical devices continues to rise, traditional thermo-optic (TO) modulation ...
