We derive the mean squared error (variance) of a blind channel estimator that exploits constraints imposed on valid combinations of code bits (also called ’logic strings’) and the respective receive symbols by the parity check equations of a channel code. The dependence of the estimation error on the length of the logic strings, their available number as(More)
Understanding a word in context relies on a cascade of perceptual and conceptual processes, starting with modality-specific input decoding, and leading to the unification of the word's meaning into a discourse model. One critical cognitive event, turning a sensory stimulus into a meaningful linguistic sign, is the access of a semantic representation from(More)
Converging evidence in neuroscience suggests that syntax and semantics are dissociable in brain space and time. However, it is possible that partly disjoint cortical networks, operating in successive time frames, still perform similar types of neural computations. To test the alternative hypothesis, we collected EEG data while participants read sentences(More)
