In this paper, a performance comparison of resolution policies specific to optical burst switching is presented. A framework, based on a reduced-load approximation, is developed to estimate path blocking probabilities in an optical burst switching network of arbitrary topology, in which any combination of the following resolution policies is in place: burst deflection, burst segmentation and li...
This paper addresses virtual reference adaptive switching control whereby a datadriven supervisor aims at stabilizing an unknown time-invariant dynamic system by switching at any time in feedback with system one element from a finite family of candidate controllers. Under the only assumption of problem feasibility, viz. the controller family contains a stabilizing controller, the resulting swit...
In this paper, we present a “deep pole assignment method” to study the observer-based stabilization of switching linear systems where the dynamics of each mode are known a priori but the switching times of modes are arbitrary. The design can be used for both 8nite and in8nite switched linear systems. We emphasize our paper on the case where the switchings of the observer and controller do not c...
The problem of L2 gain for a class of linear discrete switched systems with disturbance input is considered in this paper. It is assumed that not all of the subsystems have normal L2 gain. Based on the average dwell time method, we search for switching signals to make the switched systems achieve the weighted L2 gain. As a special case, the criterion of normal L2 gain under arbitrary switching ...
immature nature of optical logic devices and the limitations associated with optical buffering provide significant incentive to reduce the routing complexity and avoid optical domain contentions. This paper examines how the Manhattan Street Network (MSN) may be used to facilitate optical packet switching over arbitrary physical topologies. Several pertinent novel costs are introduced. Simulated...
This note shows that regime switching nonlinear autoregressive models widely used in the time series literature can exhibit arbitrary degrees of long memory via appropriate definition of the model regimes.
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
In this paper, we explore reduced-connectivity radio frequency (RF) switching networks for reducing the analog hardware complexity and switching power losses in antenna selection (AS) systems. In particular, we analyze different hardware architectures for implementing the RF switching matrices required in AS designs with a reduced number of RF chains. We explicitly show that fully-flexible swit...
We study continuous-time switched linear systems with unobserved and exogenous mode signals. We analyze the observability of the initial state and initial mode under arbitrary switching, and characterize both properties in both the autonomous and non-autonomous cases.
In multicarrier systems, the transmitted timedomain signal exhibits large amplitude peaks. This peak-toaverage power ratio (PAPR) problem complicates the practical use of multicarrier systems: the amplifier used to transmit the signal saturates because of the large peaks and causes non-linear distortion. As this non-linear distortion frustrates severely the detection of the multicarrier signal,...
