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 ...

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, ...

Portable wireless devices are becoming smaller, lighter, and more powerful with each new generation of cell phone technology. In the eyes of users, this trend is a wonderful addition. For designers, ...

Optical communication systems have evolved significantly over recent years with the advent of advanced modulation techniques designed to enhance spectral efficiency and mitigate interference. Offset ...

Important efficiency requirements exist on both the handset and the base-station sides of the telecom world. In handsets, efficiency directly translates into battery life. By increasing cell-phone ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Unless you design EDGE or 3G/UMTS cell phone handsets, you may not have heard of polar modulation. As you know, there are only a few basic types of modulation, but they have been used in a variety of ...

How it works: Backscattering allows devices to modulate and reflect incoming wireless signals back to the transmitter, similar to how RFID chips and contactless payment cards work by harvesting energy ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

5G New Radio (5G NR) is the wireless standard defining the next generation of mobile networks. 5G will offer higher capacity than current 4G, enabling a higher density of mobile broadband users and ...

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, ...
