Gradient algorithms are widely used in adaptive tapped delay-line filters, such as equalizers, to derive a set of tap coefficients that gives the desired output with a minimum mean square error (mm
Telecommunications service providers have become acutely aware of the need for fast restoration of traffic in response to cable cuts or other failures.
The need for faster and higher-capacity networks that can sustain modern, high-demanding applications has driven the development of 5G technology.
We consider a queue fed by a large number, say n, of on-off sources with generally distributed on-and off-times.
With the recent increase in the price of gold and other precious metals, new ways are being investigated to reduce the consumption of these materials.
Offloading traffic to small cells is one of the key enablers in achieving high peak data rates in a heterogeneous cellular network deployment.
This paper addresses the critical problem of high overhead in channel information acquisition for hybrid precoding in massive multiple-input multiple-output (MIMO) system.
Design, hardware, and operating software of a special purpose computer built for the Monte Carlo simulations of a wide class of random Ising spin systems is described.
Existing capacity constrained cellular networks that operate in fixed spectrum bands can be enhanced with capacity-on-demand services using the Coordinated Dynamic Spectrum Access (CDSA) model.
We demonstrate a widely tunable laser transmitter that accesses 32 ITU channels with 100 GHz spacing and switches between all channel combinations in less than 45 ns.
