This work presents a new theory of multipactor under multi-carrier signals for parallel-plate geometries. It is the generalization of the non-stationary multipactor theory for single-carrier signals1. It is valid for multicarrier signals with an arbitrary ...
The advent of multicore CPUs has led to renewed interest in software routers built from commodity PC hardware. However, fully exploiting the parallelism due to multiple cores requires the ability to efficiently parallelize the delivery of packets to cores. ...
Technology for simultaneous demultiplexing of subrate tributaries is described and applied to 320-Gb/s return-tozero input. The parametric architecture is scalable with respect to processed input rate and relies on cascaded all-optical multicasting and sub ...

Dynamical Systems (DS) are often used to represent motion, with the advantage of being easy to learn from demonstrations. We present a method to modulate DS depending on an external signal, extending our previous work on Locally Modulated DS (LMDS, Kronand ...
Sinc-shaped Nyquist-pulses possess a rectangular spectrum. Thus, a sinc-pulse transmission minimizes the carrier spacing down to the baud rate, and therefore, substantially increases the transmissible data rates. These perspectives have led to a strong res ...
This paper describes a receiver system design for impulse-radio ultra-wideband (IR-UWB) that operates at two carrier frequencies-3.494 and 3.993 GHz-with a 10-Mbps data rate. To reduce the power consumption of the front-end amplifiers, a super-regenerative ...
We demonstrate high speed optical transmission systems using digital coherent detection at all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we demonstrate a single-carrier polarization division multiplexed quadrature phase shi ...
We address the problem of joint path selection and rate allocation in multipath wireless streaming, in order to optimize a media specific quality of service. We leverage on the existence of multiple parallel wireless services, in order to enhance the recei ...
We address the problem of joint path selection and video source rate allocation in multipath streaming in order to optimize a media specific quality of service. An optimization problem is proposed, which aims at minimizing a video distortion metric based o ...
