Efficient tracking of the cross-correlation coefficient
In many (audio) processing algorithms, involving manipulation of discrete-time signals, the performance can vary strongly over the repertoire that is used. This may be the case when the signals from the various channels are allowed to be strongly positively or negatively correlated. We propose and analyze a general formula for tracking the (time-dependent) correlation between two signals. Some ...
متن کاملDysphagia Evaluation by Using Cross-correlation coefficient of Surface Electromyography
Swallowing disorder, also called dysphagia, is a common complication caused by strokes. The dysphagic patients usually have clinical problems such as choking, malnutrition, significant weight loss, and aspiration pneumonia. Surface electromyography(EMG) provides a simple, non-radioactive, and non-invasive method to measure the muscle activity patterns during swallowing to describe physiology of...
متن کاملSerial Correlation Coefficient
In this paper, we investigate the relation between two variables where the one is measured with the ratio or interval scale and the other with the nominal. In this cases, we use from serial correlation coefficient. Computation of some serial coefficient such as biserial and point-biserial coefficient is carried out with some examples and R program.
متن کاملCross-Lingual Topic Tracking using idf-Weighted Cosine Coefficient
We investigate a method of cross-lingual topic tracking which builds upon our cosine coefficient based monolingual approach. The system relies on a bilingual dictionary for translation as well as for word segmentation in the case of Mandarin. While for the true bilingual task, the system performed above average, and performed almost as well as it did over the translated-monolingual data, it per...
متن کاملEfficient Implementation of Cross-Correlation in Hardware
Low-area matched filter and correlator designs are explored in this thesis, for ADC resolutions of 1and 2-bits. Correlators are used extensively in spread-spectrum communication technologies, where they serve as a means of detecting a known pseudo-random sequence (PN code). The correlator designs presented here are intended for direct-sequence spread spectrum (DSSS) radio, where the data to be ...
