In this correspondence, the cumulants of the mutual information of the flat Rayleigh fading two-hop amplify-and-forward multiple-input multiple-output (MIMO) relay channel under independent and identically distributed (i.i.d.) Gaussian input vectors are derived in the large array limit. The analysis is based on the <i>replica</i> <i>trick</i> and covers(More)
In this paper the ergodic mutual information of the i.i.d. Rayleigh fading amplify-and-forward MIMO relay channel without direct link between source and destination is derived in the large array limit. By means of the replica method an expression is obtained, whose parameters are determined by a nonlinear equation system. This system can be solved in closed(More)
The paper describes selection rules implemented in a software generating "possible reaction mechanism", i.e. a set of elementary reactions chosen from all stoichiometrically possible reactions. The novelty of the approach lies in the fact that the user has to define all species involved (reactants, intermediates, products), and the rules applied with(More)
The sum-capacity C of a static uplink channel with n single-antenna sources and an n-antenna destination is known to scale linearly in n, if the random channel matrix fulfills the conditions for the Marcenko-Pastur law: if each source transmits at power P/n, there exists a positive c<sub>&#x03BF;</sub>, such that lim<sub>n</sub> &#x2192; <sub>&#x221E;</sub>(More)
Renju is a very old two-player board game with subtle tactics and strategies. It comes from Japan and is a professional variant of Go-Moku. In many countries, such as China, Estonia, Japan, Latvia, Russia, and Sweden, Renju is played on a high level of performance. Compared to Renju, the game of Go-Moku, mainly played in China and Japan, has rather simple(More)
