    摘要: A method of activating at least two electrodes in a multichannel electrode array using channel specific sampling sequences is presented. 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 based on parameters of spatial channel interaction reflecting geometric overlapping of electrical fields from each electrode, non-linear compression, and each electrode's weighted channel specific sampling sequence.

    摘要: A stimulation system including a stimulator having a multi-channel electrode array utilizing a monopolar electrode configuration. A processor is operatively coupled to the stimulator. The processor is configured to determine a channel interaction (CI) sequence using simultaneous, sign-correlated pulses and channel interaction compensation. The CI sequence has a CI pulse rate and a CI mean pulse amplitude, and produces resulting potentials that are substantially equal to desired potentials at given positions relative to the multi-channel array. The CI sequence may include temporal gaps between pulses, wherein the processor may be configured to increase the CI pulse rate, such that the temporal gap between pulses is decreased. Furthermore, the processor may be configured to reduce the pulse amplitude of the CI sequence while increasing pulse phase duration, such that charge per pulse remains substantially unchanged and the temporal gap between pulses is decreased.
