We provide an overview of the extensive recent results on the Shannon capacity of single-user and multiuser multiple-input multiple-output (MIMO) channels. Although enormous capacity gains have been predicted for such channels, these predictions are based on somewhat unrealistic assumptions about

Abstract. This paper examines capacity limits in mental animation of static diagrams of mechanical systems and interprets these limits within current theories of working memory. I review empirical studies of mental animation that examined (1) the relation of spatial ability to mental animation (2

Early simulation experience with wireless ad hoc networks suggests that their capacity can be surprisingly low, due to the requirement that nodes forward each others’ packets. The achievable capacity depends on network size, traffic patterns, and detailed local radio interactions. This paper

We investigate the use of multiple transmitting and/or receiving antennas for single user communications over the additive Gaussian channel with and without fading. We derive formulas for the capacities and error exponents of such channels, and describe computational procedures to evaluate

When observers are searching for a single target amongst multiple distracters, accuracy usually decreases with the number of distractors (the set-size effect). Set-size effects have been measured to seek evidence for a limit on the capacity for spatial discriminations. Experiments with unmasked

Somehow the squiggle on page 9 has become a minus sign, i.e. '~2.5 ' now reads '-2.5.' Also, the top of the radical in Equation 1 is strangely faint. It appears to *incorrectly * contain sigma. That is, the numeral 2 and the greek letter pi should appear under the radical; the greek letter sigma should not. Everything else is O.K.
