A number of variations exist to the CIS strategy.These include the Speak (Spectral
Peak; [Seligman and McDermott,1995] ),ACE (Advanced Combination Encoder;
[Vandali et al.,2000]),and other “m-of-n” strategies [Ziese et al.,2000].The main
difference of these strategies with the CIS strategy is that not all electrodes are
stimulated on a sweep over the electrodes but only a selected number of them.The
main advantage of such a reduction of stimulated electrodes is that the stimulation
rate on the selected channels can be raised and thus more temporal accuracy is
available on these selected channels.
The functional block overview of the ACE strategy is given in Figure 1.7.The ACE
scheme is the default sound processing strategy for the implant system which is
implanted the most internationally,the Nucleus CI24 implant.In comparison to the
CIS scheme an extra processing block is inserted after envelope extraction.This
block performs maxima selection,i.e.only the m most intense channels are selected
and the other channels are put to zero.In this way only m (where m varies between 6
and 12) out of the 22 channels are stimulated on each processing cycle.Because the
maximal stimulation rate of the Nucleus CI24 implant is 14400 pulses per second,
only stimulating a selected number of the 22 electrodes allows stimulating at rates
up to 2400 pulses per second and per electrode.In contrast,if no maxima selection
would be performed,as in the CIS strategy,only 650 pulses could be stimulated per
second and per electrode.This latter rate might be too low for optimal transmission
of the temporal details of speech because the pulse rate should be about 4 to 5 times
higher than the highest modulation rate in cochlear implants [McKay et al.,1994].
The second group of cochlear implant sound processors do not interleave their
pulses like the CIS strategy (or its variants).Most of these current strategies are
derived from the CA strategy [Eddington,1980].Because a great advantage was
found for CIS-like strategies over the CA strategy [Wilson et al.,1991],most recent
strategies are derived from the CIS strategy.However,the SAS strategy
implemented in the Clarion device from Advanced Bionics uses simultaneous
stimulation like the CA strategy,but also incorporates a number of features to
minimize channel interaction [Battmer et al.,1997].With this improved
simultaneously stimulating strategy performance was reported to be comparable to
the CIS strategy [Osberger and Fisher,2000].

一些差别独联体战略.这些措施包括说话（谱高峰; [塞利格曼和麦克德莫特1995 ] ） ,血管紧张素转换酶（高级组合编码器;[ Vandali等.2000 ] ） ,和其他“男的N ”的战略[ Ziese等.,2000 ] .主要这些战略的差异与独联体的战略是,并不是所有的电极刺激的横扫电极但只有若干人.那个主要优点,例如减少刺激电极刺激的是,利率选定渠道可以提高,从而更准确的时间可在这些选择的渠道.
该功能块概述了ACE的战略是在图1.7 .在ACE计划是默认声音处理的战略,这是种植体系统植入最国际的核心CI24植入.相对于独联体计划额外的处理后插入块包络提取.这个区块进行极大的选择,即只有米最激烈的渠道选择和其他渠道,把为零.以这种方式不仅米（其中m之间6和12 ）的22个频道的刺激每个处理周期.由于最大刺激率核CI24植入脉冲每秒14400 ,只有刺激一些选定的22个电极可刺激率可达2400脉冲每秒每电极.与此相反,如果没有极大的选择将执行,如在独联体国家战略中,只有650个脉冲,可刺激每第二,每电极.后者率可能太低最佳传输颞细节的讲话,因为脉搏应约4到5倍高于最高调制率在人工耳蜗植入[麦凯等.,1994 ] .
第二组的人工耳蜗植入声音处理器没有交错的豆类,如独联体国家战略（或其变体） .其中大部分目前的战略是来自加利福尼亚的战略[爱丁顿,1980 ] .由于是一个很大的优势找到独联体样的战略的CA策略[威尔逊等人.,1991 ] ,最近战略是来自独联体国家的战略.然而,战略的SAS实施克拉里昂装Advanced Bionics公司使用同步喜欢刺激的CA的战略,而且还采用了一些新的功能,尽量减少渠道的互动[ Battmer等.,1997 ] .这一改进同时刺激战略性能据报道,具有可比性独联体战略[ Osberger和Fisher ,2000 ] .
