چکیده مقاله:

In this paper, we discuss Brain-computer computer interface (BCI) and its problem of data transfer. The main object is to examine the classification of EEG signals whichare divided into two target and non-target classes and to improve the speed of BCI communication. Data is collected by the p300 speller, then a preprocessing treatment is performed on the recorded data. Since the EEG signals are low amplitude recording and averaging steps should be acted several times. Therefore, the BCI communication speed is slow. A new channel selection of electroencephalography is presented due to speed of communication. Due to the extraction of the P300 and distinction between the signal with P300 and signal without p300, we use the feature extraction. Then we classify signals using different classifiers such as RBF, SVM and ANN. Comparing analysisshows that SVM gives the best possible result among examining classifier for the BCI communication.
