{ A novel reduced-state soft-output trellis-equalization algorithm is presented, which essentially is a combined application of the algorithms of Bahl et al. and that of Lee to a reduced-state trellis. State reduction is accomplished by a feedback of soft decisions. For this, soft decisions are calculated using a reduced-state Lee algorithm. The proposed feedback is optimum in terms of mean-squ...

We compare the rate of decay singular numbers a given composition operator acting on various Hilbert spaces analytic functions unit disk D. show that for Hardy and Bergman spaces, our results are sharp. also give lower upper estimates with symbol “cusp map” lens maps, weighted Dirichlet spaces.

Wayfinding support is a basic and important location based service. Today, this kind of service is mostly provided by solidly installed, static means. Of these means maps ideally support wayfinding, as it is possible, for example, to use one map for many visitors with many different destinations. A special kind of maps––You-Are-Here maps––is especially suited if design and placement criteria ar...

Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. A Global Symbol for the Small b-Calculus on Manifolds With Boundary Thesis directed by Prof. Markus Pflaum Starting with the normal symbold of M. Pflaum ([Pfl98]), we generalize the mac...

◦ Geodesic flows on compact manifolds with negative sectional curvature. Later, we relax uniform hyperbolicity to an asymptotic one, called non-uniform hyperbolicity. Two examples of such systems are: ◦ Slow down of fA : T → T, see [9]. ◦ Geodesic flows on surfaces with nonpositive curvature. Introductory example: Smale’s horseshoe [21]. Let g : K → K be Smale’s horseshoe map, and σ : Σ→ Σ the ...

In this short note we have discussed generalized shift map in the symbol space Σ2. Some stronger chaotic properties have been proved. Some special properties are discussed in a different section. In the last section we have also provided few examples.

The present paper analyzed the perception of spatial dispersion in the distribution of point objects. Spatial dispersion is one of the major concepts communicated by dot maps. To promote efficient communication of this concept, two experiments were conducted for investigating the relationship between the perception of spatial dispersion and the following map characteristics: spatial arrangement...

In recent years, soft iterative decoding techniques have been shown to greatly improve the bit error rate performance of various communication systems. For multiple antenna systems employing spacetime codes, however, it is not clear what is the best way to obtain the soft-information required of the iterative scheme with low complexity. In this paper, we propose a modification of the Fincke-Poh...

As a tool for human spatial cognition and thinking, the map has been playing an important role. Maps are perhaps as fundamental to society as language and the written word. Economic and social development requires extensive and in-depth understanding of their own living environment, from the scope of the overall global to urban housing. This has brought unprecedented opportunities and challenge...
