A central assumption is that social capital - as a resource - is emerging from the quality of these relationships. This quality may be described in a more materialistic sense because these relations open up access to specific resources or assets. But it may also be imbued with valuated connotations, in particular referring to the essential contribution of networks and trust in promoting well-being, a sense of belonging and decency as individuals in entities blessed with social capital are pretended to engage in mutually beneficial collective actions. Therefore social capital applies to peoples’ shared expectations, norms, values, and beliefs, their commitments to each other and eventually their associative capacities to knit the ‘social fabric’. }}, author = {{Landhäußer, Sandra and Ziegler, Holger}}, journal = {{Social Work & Society}}, keywords = {{Social Capital}}, publisher = {{Social Work and Society International Online Journal}}, title = {{{Social Capital}}}, doi = {{https://ejournals.bib.uni-wuppertal.de/index.php/sws/article/view/187}}, volume = {{4}}, year = {{2006}}, } @inbook{40426, author = {{Grotjahn, Rebecca}}, booktitle = {{La cité céleste.

To avoid the in- herent ambiguities of this problem, the spatial correlation matrix of the source signals must be non-white and known at the receiver. In practice, this can be achieved by a number of simple linear preco- ding techniques at the transmitter side. More specifically, it is shown in the paper that if the source correlation matrix has different eigen- values, then the decoding process can be formulated as the problem of maximizing the sum of a set of weighted variances of the signal estimates. Exploiting the special structure of OSTBCs, this problem can be reduced to a principal component analysis (PCA) problem, which allows us to derive computationally efficient batch and adap- tive blind decoding algorithms. The algorithm works for any OSTBC (including the popular Alamouti code) with a single receive antenna.

There are two alternative design objectives: minimizing the trace of the error correlation matrix and thus minimizing the mean-squared error, or minimizing the determinant of the error correlation matrix and thus maximizing information rate. It is shown that a solution to both problems is to first transform the noisy observations into canonical coordinates, quantize and apply a Wiener filter in this coordinate system, and then transform the result back to the original coordinates. Canonical coordinates are uncorrelated, and quantization and Wiener filtering are applied to each component independently. The type of canonical coordinate system depends on the design objective: Quantization in half-canonical coordinates minimizes the mean-squared error and quantization in full-canonical coordinates maximizes information rate.
