Abstract: | Brain Computer Interface (BCI) is an external channel from brain to the human organs. Therefore, BCI facilitate the disabled people to move their limbs. Electroencephalogram (EEG) is one of BCI recording signals which has high temporal resolution with low spatial resolution. Some researchers proposed common spatial filters to overcome the spatial resolution deficiency. However, these filters are highly sensitive to the CSP frequency band and, may decline the BCI performance. Many researchers increased the BCI performance by using filter bank CSP. They utilized a bank of band-pass filters to separate CSP in each band. However selecting of the number and the range of each frequency band becomes troubles ome.In this research work we utilized FBCSP with flexible overlapping frequency bands to enhance the decoding mental activities performance. The simulation results indicate that our proposed technique provides better classification performance (κ=0.62 with respect to the best κ=0.57 for the winner). |
