Speech and audio coding are often considered to be two separate technologies each almost independently developing different techniques for signal compression.
Unlocking the true potential of massive antenna arrays for cellular networks operating in frequency division duplex (FDD) mode is a challenging task as inadequate channel state information (CSI) by
Third generation CDMA systems will simultaneously support traffic with different data rates, such as data and voice traffic.
A macroscopic two degree-of-freedom (2Dof) nonlinear energy harvester, which employs velocity amplification to enhance the power scavenged from ambient vibrations, is presented.
Vibrational energy harvesting has become relevant as a power source for the reduced power requirement of electronics used in wireless sensor networks (WSNs).
A macroscopic two degree-of-freedom (2Dof) nonlinear energy harvester, which employs velocity amplification to enhance the power scavenged from ambient vibrations, is presented.
A MULTIPLE UNIT STEERABLE A NT EN NA 339 If, however, the directivity can be varied or "steered" to meet the various conditions imposed by nature, a new field is opened in which a new order of ante
Vibrational energy harvesters (VEHs) are devices which convert ambient vibrational energy into electrical power, offering an alternative to batteries for powering wireless sensors.
We use magnetic field and riometer data, from ground observatories in both the Arctic and Antarctic regions to characterize the high-latitude propagation of a sudden storm commencement (SC) that oc
We report a hierarchical optical add-drop multiplexer (OADM) network that supports 10-, 40-, and 160-Gb/s data rates with the same bandwidth efficiency.
