A further point of potential importance is the enrichment of communications, in terms of additional words, utterances, speech acts, and communication sequences.
"This isn't a matter of ego or crowing," says Steve Crocker, who was present that day at UCLA in 1969, "but there has not been, in the entire history of mankind, anything that has changed so dramatically as computer communications, in terms of the rate of change".
The Rail-CR cognitive radio will enhance the performance of railway communications in terms of interoperability, robustness, reliability, and spectral efficiency, and will make it cost-effective to deploy and maintain.
Green cellular networks (see, e.g., [3, 4]), which aim at optimizing energy efficiency (EE) for communications in terms of bits per joule per hertz have drawn considerable research interests in recent years (see, e.g., [5 8] and the references therein).
Results in [6] show that the problem with this approach is that several competing tasks running in parallel with QAM may hurt the performance of the modulation, making this approach inadequate for demanding wireless communications in terms of throughput and energy efficiency.
With this understanding, clinicians and patient advocacy organizations should focus on the quality of their communications in terms of presenting a balanced account of risks, benefits, and the state of research advances, rather than attempting to manage patient expectations.
In [108], authors define QoS requirements for general smart grid communications using in terms of communication delays and outage probability.
The application of left inverses in Eq. (16) improves the capacity/robustness of the wireless communications network in terms of the elimination of the parasitic impact of noise.
Intelligence is needed to keep up with the rapid evolution of wireless communications, especially in terms of managing and allocating the scarce, radio spectrum in the highly varying and disparate modern environments.
We review how CR technologies such as dynamic spectrum access, adaptive software-defined radios, and cooperative communications will enhance vehicular communications and, hence, present the potential of transforming vehicle communication in terms of efficiency and safety.
Zaller argues that "flow of political communications" can be seen in terms of two models, a "two-message model" in which the pronouncements of political leaders divide along partisan lines leading to a polarization of public opinion and a "one-message model" in which they do not.
