Today's cellular systems are designed to achieve 90-95 percent coverage for voice users (i.e., the ratio of signal to interference plus noise must be above a design target over 90 to 95 percent of
The interface between technology and people has long been the focus of human factors engineering.
In a frequency division duplex system, a transmitter adaptive antenna array can potentially improve the performance of a wireless downlink, but because the uplink and downlink channels have differe
As software development becomes more collaborative, business and technical processes of software engineering and their management need to accommodate and support collaboration.
We consider the problem of inferring link loss rates using passive measurements. Prior inference approaches are mainly built on the time correlation nature of packet losses.
This paper discusses the possibility to apply Passive Optical Network (PON) mechanisms in the metropolitan area.
We investigate a MIMO system that uses linear MMSE receiver processing to separate the spatial streams.
A two-channel structure consisting of multiple cascades of allpass filters and directional couplers has certain desirable attributes.
In this paper, we investigate algorithms for solving generalized eigenvalue problems that arise in the context of signal enhancement.
Algorithms and software for proactive and adaptive detection of network/service anomalies (i.e., performance degradations) have been developed, implemented, deployed, and field-tested for transacti
