Bounds on maximum throughput for digital communications with finite-precision and amplitude constraints
Digital communications data rate linear impulse response
2015/8/12
The problem of finding the maximum achievable data rate over a linear time-invariant channel is considered under constraints different from those typically assumed. The limiting factor is taken to be ...
On optimal signal sets for digital communications with finite precision and amplitude constraints
Signal collection digital communications data rate the time-varying dispersive channel data rate
2015/8/12
The maximum data rate that can be reliably communicated given a linear, time-invariant, dispersive channel, a receiver that samples the channel output to within an accuracy of pm d, where dgeq 0, and ...
A tractable method for robust downlink beamforming in wireless communications
Wireless communication system sound localization noise signal interference ratio
2015/8/10
In downlink beamforming in a multiple-input multiple-output (MIMO) wireless communication system, we design beamformers that minimize the power subject to guaranteeing given signal-to-interference noi...
The globalization of Internet access and Web 2.0 services has led to profound changes in the nature and context of communications. Traditionally, communication meant to transmit a message to a certain...

Information communications and technology (ICT) is transforming the environment in which SMEs operate and changing the paradigms of value creation, customer satisfaction and business effectiveness. Th...
Patterns of Programmers' Use of Computer-Mediated Communications Systems
Programmers Computer-Mediated Communications Systems
2009/12/8
Communication behavior of programmers plays an essential role in success of software development. Computer-mediated communication (CMC) system, such as e-mail, or the World Wide Web (WWW), have substa...
UMTS-HSDPA in High Altitude Platforms (HAPs) Communications
HAPs W-CDMA UMTS HSDPA Carrier-to-interference ratio
2009/7/28
In this paper, the performance of HAPs (High Altitudes Platforms) UMTS HSDPA (High Speed Downlink Packet Access) is studied for different HAPs height h, different cells radius R and two directions (0°...
