چکیده

A Brain Computer Interface (BCI) system allows the users to communicate with their surroundings without using any muscle activity. Many of these systems are based onthe analysis of Event Related Potentials (ERPs) such as P300. P300 speller is one of the common BCI systems which attract alot of attention; however, there are still a lot of flaws in these systems which should be considered. Since ERPs such as P300signals have a very low Signal to Noise Ratio (SNR), singletrial analysis of these signals is difficult and in many papers, denoising methods such as synchronous averaging wereproposed to reduce random noise; however, it reduces the communication rate greatly. Another major problem in manyBCI applications is the numerous number of channels needed to record EEG signals in order to have a reliable system. In this paper, a new method is presented to detect P300 signals through single channel data analysis and also it reaches an average accuracy of 65% in single trial P300 detection

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
