On the Sum Capacity of Many-to-one and One-to-many Gaussian Interference Channels
We obtain new sum capacity results for the Gaussian many-to-one and one-to-many interference channels in channel parameter regimes where the sum capacity was known only up to a constant gap. Simple HanKobayashi (HK) schemes, i.e., HK schemes with Gaussian signaling, no time-sharing, and no common-private power splitting, achieve sum capacity under the channel conditions for which the new result...
متن کاملThe Capacity of Mixed and One-Sided Gaussian Interference Channels
This paper adds to the understanding of the capacity region of the Gaussian interference channel. To this end, the capacity region of the one-sided Gaussian interference channel is first fully characterized. This is accomplished by introducing a new representation of the Han-Kobayashi region and providing a new outer bound on the capacity region of this channel which is tight both in the weak a...
متن کاملInterference Alignment and a Noisy Interference Regime for Many-to-One Interference Channels
We study the capacity of discrete memoryless many-to-one interference channels, i.e., K user interference channels where only one receiver faces interference. For a class of many-to-one interference channels, we identify a noisy interference regime, i.e., a regime where random coding and treating interference as noise achieves sum-capacity. Specializing our results to the Gaussian MIMO many-to-...
متن کاملOne Way to Select Many
Selecting items from a collection is one of the most common tasks users perform with graphical user interfaces. Practically every application supports this task with a selection feature different from that of any other application. Defects are common, especially in manipulating selections of non-adjacent elements, and flexible selection features are often missing when they would clearly be usef...
متن کاملFrom one cell to many
embryo undergoes several synchronized nuclear divisions without cytokinesis, to form a 'syncytial blastoderm'. During these divisions, the nuclei migrate to the cortex of the embryo where the last few divisions take place before cellularization. The dividing nuclei at lower right are all synchronized at metaphase. Mitotic spindles are stained red; DNA is stained green. At cellularization, the o...
