Distortion in feedback amplifiers has previously been studied for the ease where the feedback is independent of frequency.

A transmitter without channel state information wishes to send a delay-limited Gaussian source over a slowly fading channel.

Applying high magnetic fields parallel to the surface of a high-mobility 2D electron gas, we have recently observed a transition from the fractional quantum Hall liquid to an insulating phase, for

Weak optical feedback is observed to cause large deviations from flat frequency modulation response in 1.5microns DFB lasers.

Significant shape distortion has been observed when an ultrashort pulse is total internally reflected from an interface.

An expression is given for the FM distortion introduced by a transducer whose attenuation and phase shift depend upon the frequency in an arbitrary way.

Mobile network operators are considering caching as one of the strategies to keep up with the increasing demand for high-definition wireless video streaming.

we review digital techniques used in transmission through telecom fibres and show they can be tailored to Distributed Acoustic Sensing (DAS), with key advantages in terms of noise floor and of scal

We examine threshold-based transmission strategies for distributed opportunistic medium access in a scenario with fairly general probabilistic interference conditions.

A majority of network-level utility optimization problem can be formulated as, transformed or reduced to a nonconvex Weighted Sum-Rate Maximization (WSRM) problem with respect to power optimization
