Capacities of time-varying multiple-access channels with side information

Capacities of time-varying multiple-access channels with side information

We determine the capacity regions for a class of timevarying multiple-access channels (TVMACs), when the underlying channel state evolves in time according to a probability law which is known to the transmitters and the receiver. Additionally, the transmitters and the receiver have access to varying degrees of channel state information (CSI) concerning the condition of the channel. Discrete-tim...

Distortion Exponent in MIMO Fading Channels with Time-Varying Source Side Information

Transmission of a Gaussian source over a timevarying multiple-input multiple-output (MIMO) channel is studied under strict delay constraints. Availability of a correlated side information at the receiver is assumed, whose quality, i.e., its correlation with the source signal, also varies over time. A block-fading model is considered for the states of the time-varying channel and side informatio...

Outage Capacities of Broadcast Fading Channels with Channel Side Information under Different Spectrum-sharing Techniques

We derive the outage capacity regions of fading broadcast channels for code-division (CD), time-division (TD) and frequency-division (FD), assuming that both the transmitter and the receivers have perfect channel side information. The zero-outage capacity regions and the associate optimal resource allocation policies are obtained for CD with and without successive decoding, for TD and for FD. W...

A Multi-objective optimization model for project scheduling with time-varying resource requirements and capacities

Proper and realistic scheduling is an important factor of success for every project. In reality, project scheduling often involves several objectives that must be realized simultaneously, and faces numerous uncertainties that may undermine the integrity of the devised schedule. Thus, the manner of dealing with such uncertainties is of particular importance for effective planning. A realistic sc...
