The self-organizing map is an algorithm which can be used to establish the presence of various categories in a given numerical and non-numerical data and to visualize the complex topographical relations between the various such categories in a low dimensional and easily comprehensible display. In this paper, SOM has been used to visualize the output of a wireless channel in the presence of inte...

Most spatial modulation (SM) schemes in the literature use hard-output maximumlikelihood (ML) antenna index detection. In trellis coded spatial modulation (TCSM) scheme, the detection should be also performed for the transmitted symbol, while the sequence decoding is performed using a hard-output Viterbi algorithm. We modified the hard-output ML-SM detector to determine a soft estimate of the t...

The paper describes research and preliminary results relating to an auxiliary data structure for modelling space in map generalisation research. The representation is based on a regular grid that is then aligned with linear cartographic features, such that the topology of the grid and the topology of the features is shared. The author first outlines the motivation for using the structure in rel...

We consider subshifts of nite type on the symbol space generated by incidence matrices over a countably innnite alphabet. We extend the deenition of topological pressure to this context and, as our main result, we construct a new class of Gibbs states of HH older continuous potentials on these symbol spaces. We establish some basic stochastic properties of these Gibbs states: exponential decay ...
