An approach to adaptive beamforming in measurement of EEG.Proceedings 2nd European Medical and Biological Engineering Conference.EMBEC´02.Pt.2
PublikacjaPotencjały wywołane są wykorzystywane w diagnostyce narządów zmysłu. Ze względu na niski SNR wymagana jest wielokrotne powtarzanie stymulacji i uśrednianie wyników. Prowadzi to do zwielokrotnienia czasu badania. SNR może zostać poprawiony przy użyciu matrycy sensorów. Są one wykorzystane do śledzenia źródeł sygnału. W publikacji przedstawiono dwie metody adaptacyjnego poprawania współczynnika SNR.
