We correct some expressions obtained in the above paper. The corrected expressions will be useful for evaluating the channel capacity of wireless communication systems over fading channels.

The problem of capacity achieving (optimal) input probability measure (p.m.) has been widely investigated for several channel models with constrained inputs. So far, no outstanding generalizations have been derived. This paper does a forward step in this direction, by introducing a set of new requirements, for the class of real scalar conditional output p.m.’s, under which the optimal input p.m...

In this paper, we show that the capacity of the threenode Gaussian relay channel can be achieved to within 1 and 2 bit/sec/Hz using compress-and-forward and amplify-and-forward relaying, respectively.

Optimal actions of an agent facing a Shannon capacity constraint on the translation of an uncertain signal into an action can easily turn out to be discretely distributed, even when the objective function and the initial distribution of uncertainty contain no discrete elements. We show this result analytically in a broad class of cases. It has implications for the interpretation of observed int...

In 2005, the Ministry of Health (MoH) in Mongolia initiated the process of developing its Health Sector Strategic Master Plan (HSSMP), using a wide-ranging consultative process, driven by the MoH, and requiring participation from all levels of health facilities, other ministries, donor agencies and NGOs. Among other objectives, the MoH sought to coordinate the disparate inputs from key donors t...

We discuss the di erent ways of de ning channel capacity for certain types of illicit communication channels. We also correct some errors from the literature, o er new proofs of some historical results, and give bounds for channel capacity. Special function techniques are employed to express the results in closed form. We conclude with examples.

Good theoretical values for vital capacity (VCt) can be used to calculate a VC/VCt ratio which remains constant for a given individual subject throughout different growth periods. This longitudinal study on 27 boys was performed in order to determine whether a single equation was accurate throughout the growth of boys. The mean values of VC/VCt were also compared for the beginning and end of th...

—This paper presents a comparison between the outage capacity of MIMO channels predicted by the Kronecker and Müller models as a function of the number of scatterers, transmit and receive antennas. The Müller model is based on the single-scattered rays between arrays of transmit-and receive antennas, while the Kronecker model considers only double scattering. The channel capacity predictions by...
