| 中文摘要: |
| 基于混响信号统计模型，建立一种原理简单、易于实现的混响信号仿真算法，针对高频窄带信号引用椭圆滤波器进行滤波，仿真结果表明，该方法产生的混响信号无论在形式上还是统计特性上和理论分析结果都有很好的一致性，并分析了混响信号的相关、时频分布特性。 |
| 英文摘要: |
| A practical method of simulating reverberation signal based on the statistical model was presented in which ellipse filter was employed to filter the high frequency narrowband signal. Simulation results showed that the simulated reverberation signal was well accordant with theoretical conclusion on both signal pattern and statistical characteristics. Moreover, other characteristics of reverberation signal such as correlation and energy distribution in time-frequency field were also summarized in this paper. |
