In this paper, a reduced complexity soft-input soft-output MIMO detector is presented. The detector is intended to be used in conjunction with an error correction code. The detector combines a Sphere Decoder with a Hopfield network to calculate a max-log-map approximation. It is then combined with the error correction code in an iterative structure(More)
Single-view distributed video coding (DVC) is a video compression method that allows for the computational complexity of the system to be shifted from the encoder to the decoder. The reduced encoding complexity makes DVC attractive for use in systems where processing power or energy use at the encoder is constrained, for example, in wireless devices and(More)
The author discusses the relationship between a pastoral hermeneutics and the current social context as determined by international communication and globalization. He explores the influence of telecommunications on the human quest for meaning and the implication of this for pastoral care and counseling. A paradigm shift is proposed in terms of care to the(More)
Single view distributed video coding (DVC) is a coding method that allows for the computational complexity of the system to be shifted from the encoder to the decoder. This property promotes the use of DVC in systems where processing power or energy use at the encoder is constrained. Examples include wireless devices and surveillance. This paper extends on(More)

It is argued that habitus plays a fundamental role in both a practical theological and pastoral-anthropological approach in order to focus on the “wholeness” of the human soul (soul as a qualitative and relational entity). It is hypothesized that a spiritual understanding of fortigenetics and the emphasis on a positive growth model can help pastoral(More)
In this paper, a reduced complexity soft-input softoutput MIMO detector is presented. The detector combines a Sphere Decoder, a Hopfield neural network and an error correction code in an iterative structure (turbo). The simulation results demonstrate that with less computational complexity, the proposed system’s performance equals that of a sphere decoder(More)
In this paper, the effects of quantization on the achievable diversity of a linearly precoded Space-Time-Frequency (STF) and Space-Frequency (SF) coded MIMO-OFDM system are studied. A relationship between the maximum achievable diversity in a linearly precoded system and the number of quantization bits is derived. The performance of two different STF codes(More)
The most important question in biomedical ethics is really whether a researcher should do what he can do. The interventional model of modern medicine, which makes medical decisions on medical grounds, can threaten human values. In a Christian perspective we are responsible to God for our humanity. Surrogate motherhood is a very complicated question which(More)
