On Time Reduction and Simulation in Cellular Spaces
, 1998
"... We prove a generalized and corrected version of the time reduction theorem for cellular spaces. One basic tool for investigations in this field is the concept of simulation between systems of automata. We propose a general formal definition of the intuitive concept and relate it to the notions whic ..."

Cooperative diversity in wireless networks: efficient protocols and outage behavior
 IEEE TRANS. INFORM. THEORY
, 2004
"... We develop and analyze lowcomplexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks. The underlying techniques exploit space diversity available through cooperating terminals’ relaying signals for one another. We outline several strategies ..."

for physical arrays, though at a loss of spectral efficiency due to halfduplex operation and possibly at the cost of additional receive hardware. Applicable to any wireless setting, including cellular or ad hoc networks—wherever space constraints preclude the use of physical arrays—the performance
Motivic Decomposition of Relative Cellular Spaces
, 2008
"... We show that for any cohomology theory A endowed with characteristic classes the Amotive of a relative cellular space X decomposes into the direct sum of twisted motives of base spaces. In particular, the Acohomology of X decomposes into the direct sum of cohomology of base spaces. Obtained result ..."

HighRate Codes that are Linear in Space and Time
 IEEE Trans. Inform. Theory
, 2000
"... Multipleantenna systems that operate at high rates require simple yet effective spacetime transmission schemes to handle the large traffic volume in real time. At rates of tens of bits/sec/Hz, VBLAST, where every antenna transmits its own independent substream of data, has been shown to have good ..."

Oriented cohomology and motivic decompositions of relative cellular spaces
 J. OF PURE AND APPLIED ALGEBRA
, 2004
"... For an oriented cohomology theory A and a relative cellular space X, we decompose the Amotive of X into a direct sum of twisted motives of the base spaces. We also obtain respective decompositions of the Acohomology of X. Applying them, one can compute A(X), where X is an isotropic projective homo ..."

SelfReproduction in a Reversible Cellular Space
 Comput. Sci
, 1996
"... We investigate a problem whether selfreproduction is possible in a twodimensional "reversible " cellular space, and give an affirmative answer. A reversible (or injective) cellular automaton (RCA) is a CA such that every configuration has at most one predecessor. In order to design an RC ..."

Games on Cellular Spaces: An Evolutionary Approach
"... Abstract. By using differential equations, evolutionary game theory shows that most of the games of competition for resources have equilibrium strategies named Evolutionary Stable. Although this approach can deduce these points, it is not possible to say how or whether a population will reach such e ..."

such equilibrium. We present an evolutionary agentbased model where individuals compete for space using mixed strategies. Agents belong to spatial locations that settle with whom they can interact, but they can freely move to contiguous partitions according to a definition of satisfiability. The simulation
Selfreproduction in threedimensional reversible cellular space
 Artificial Life
, 2002
"... Due to inevitable power dissipation, it is said that nanoscaled computing devices should perform their computing processes in reversible manner. This will be a large problem in constructing threedimensional nanoscaled functional objects. Reversible cellular automata (RCA) are used for modeling ph ..."
