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 ...

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 ...

DENVER — A small startup claiming breakthroughs in phase-coherent filter modulation will be demonstrating its signal-processing techniques in analog pager bands later this year, as a prelude to ...

This chapter covers the following subjects: Wireless Local-Area Networks: A brief history of wireless networking and some of the basic concepts. How Bandwidth Is Achieved from RF Signals: The ...

This paper is the study of the QPSK (Quadrature Phase Shift keying) modulation technique using AWGN (Additive White Gaussian Noise) and Multipath Rayleigh fading channel. In QPSK scheme the authors ...

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 ...

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, ...

In addition to radar sensing capabilities, this IR-UWB transceiver offers another feature that sets it apart from existing ...

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 ...

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 ...
