Abstract

Abstract:

In three-dimensional sound reproduction with two speakers, Crosstalk Cancellation System (CCS) performance optimization often pay more attention to the effect independently by the factors such as inverse filter parameters design and loudspeaker configuration. A frequency-domain Least-Squares (LS) estimation approximation was proposed to use for the performance optimization. The relationship between these factors and their effect on CCS performance was evaluated systematically. To achieve the tradeoff of computing efficiency and system performance of crosstalk cancellation algorithm, this method obtained the optimization parameters. The effect of crosstalk cancellation was evaluated with Channel Separation (CS) and Performance Error (PE) index, and the simulation results indicate that these parameters can obtain good crosstalk cancellation effect.

摘要：

针对三维声音两扬声器重放中基本上独立研究逆滤波器的设计或扬声器的配置等因素对串声消除系统（CCS）性能的影响，提出了采用频域最小均方（LS）估计逼近方法，系统考察这些因素之间的关联以及对串声消除性能优化的作用，并通过折中考虑CCS的运算效率及系统性能获得了一组最优参数。实验采用通道分离度（CS）和性能误差（PE）两个指标对串声消除效果进行综合评价，仿真结果表明，该组最优参数能获得很好的串声消除效果。
