ABSTRACT:
A method of activating at least two electrodes in a multichannel electrode array uses channel specific sampling sequences. More particularly, a channel specific sampling sequence is defined for each electrode, the sequence having a particular duration, pulse amplitude distribution, and number of pulses. A weighting factor is applied to the channel specific sampling sequence. Each electrode in the multichannel electrode array is then simultaneously activated using sign-correlated pulses. The sign-correlated pulses are based on parameters of spatial channel interaction reflecting geometric overlapping of electrical fields from each electrode, wherein calculating the amplitudes of the sign-correlated pulses includes compensating for geometric overlapping of electrical fields from each electrode. Furthermore, the sign-correlated pulses are based on each electrode's weighted channel specific sampling sequence.
