Introduction: ECOC 2012 in Amsterdam.
We introduce the Optics Express special issue from the 38th European Conference on Optical Communication and Exhibition (ECOC). A total of 134 expanded papers from ECOC 2012 are included in this special issue.
متن کاملOptical LDPC decoders for beyond 100 Gbits/s optical transmission.
We present an optical low-density parity-check (LDPC) decoder suitable for implementation above 100 Gbits/s, which provides large coding gains when based on large-girth LDPC codes. We show that a basic building block, the probabilities multiplier circuit, can be implemented using a Mach-Zehnder interferometer, and we propose corresponding probabilistic-domain sum-product algorithm (SPA). We per...
متن کاملSpeed-Area Trade-off for 10 to 100 Gbits/s Throughput AES Processor
This paper explores the area-throughput trade-off for an ASIC implementation of the Advanced Encryption Standard (AES) algorithm in a 0.18 μm CMOS technology. Three different pipelined implementations of the AES algorithm are presented which provide a throughput range between 15.7 to 77.6 Gbits/s with an area cost of 116 to 473 Kgates. Therefore, the AES algorithm in the counter mode of operati...
متن کاملFLIP-ECOC: A Greedy Optimization of the ECOC Matrix
Error Correcting Output Coding (ECOC) is a multiclass classification technique, in which multiple base classifiers (dichotomizers) are trained using subsets of the training data, determined by a preset code matrix. While it is one of the best solutions to multiclass problems, ECOC is suboptimal, as the code matrix and the base classifiers are not learned simultaneously. In this paper, we show a...
متن کاملVijendravarma et al 2012 PRSB (Preprint version)
Chronic exposure to food of low quality may exert conflicting selection pressures on foraging behaviour. On the one hand, more active search behaviour may allow the animal to find patches with slightly better, or more, food; on the other hand, such active foraging is energetically costly and thus may be opposed by selection for energetic efficiency. Here we test these alternative hypotheses in ...
