Perceptual judgment and saccadic behavior in a spatial distortion with briefly presented stimuli.
When observers are asked to localize the peripheral position of a small probe
with respect to the mid-position of a spatially extended comparison stimulus,
they tend to judge the probe as being more peripheral than the mid-position of
the comparison stimulus. This relative mislocalization seems to emerge from
differences in absolute localization, that is the comparison stimulus is
localized more towards the fovea than the probe. The present study compared
saccadic behaviour and relative localization judgements in three experiments and
determined the quantitative relationship between both measures. The results
showed corresponding effects in localization errors and saccadic behaviour.
Moreover, it was possible to estimate the amount of the relative mislocalization
by means of the saccadic amplitude
Turbo-blast and its performance
Research has shown that the performance of demapping a multilevel modulated signal can be improved by using anti-Gray mapping and iterative demapping and decoding. Iterative demapping and decoding is based on the turbo-decoding principle. In order to improve the performance of the multi-input multi-output (MIMO) Bell-Labs Layered Space Time (BLAST) wireless communication algorithm, the combination of BLAST and iterative decoding is examined. This principle is called turbo-BLAST. Turbo-BLAST is evaluated using the extrinsic information transfer (EXIT) chart method
