Thank you, Mr Makoto!
I will try this plugin(clean_rawdata). If my result SNR improve significantly, I will give you feedback:)

Dear Booer,

ICA can be severely compromised by 'bad data'. Use very aggressive cleaning & filtering, obtain ICA matrix, and apply it back to the moderately cleaned & filtered data may work.

Use clean_rawdata() and use ASR threshold 20, which produced the best results out of 19 other methods we compared (unpublished!) Check the EEGLAB plugin manager or download it from http://sccn.ucsd.edu/wiki/Plugin_list_process

Hello, everyone.
        In eeglab, ICA and bandpass are good to improve single trial SNR. Are there some other "good methods"(it shoud better have some toolboxs) to improve SNR? 

Thank you!
