摘　　要：基于滤波器组分频的波形策略是电子耳蜗语音处理策略中重要的一类方案。利用Matlab中的Simu-link建模工具,对该策略的连续交替采样算法(Continuous Interleaved Sampling Approach CIS)进行简化建模仿真。并根据汉语频率范围和硬件实现的要求,对算法中关键部分滤波器组分频模块进行改进。最后通过仿真直观地验证该模型的合理性与可靠性。Waveform strategy based on frequency demultipcation with filter bank is an important category of speech processing strategies. This article took the continuous interleaved sampling approach （CIS） which is one of the waveform strategies, and proposed its simplified simulation model with simulink. According to the frequency range in Chinese and requirement of hardware implement,we imploved the key filter bank module. The validity and rationality of the model was confirmed by this model with simulation.
