| 摘 要： | 对卷积混叠信号盲分离过程中解决顺序模糊的方法进行了探讨，提出了一种利用麦克风嵌套子阵列，结合DOA法和相关法的更加稳健的纠正顺序不确定性的算法。仿真结果表明，利用基于麦克风嵌套子阵列的频域盲反卷积算法能够有效地解决DOA方法在低频段有效性较差、频域盲反卷积算法中低频段的顺序模糊问题。

| Abstract: | In this paper,we present a new method for solving the permutation problem using microphone sub-arrays.,which is based on the combination of direction of arrival(DOA) estimation for sources and the inter-frequency correlation of signal envelopes.Firstly,DOA estimation is performed using microphone sub-arrays so that the permutation problem is solved more robustly in low frequencies.Secondly,we exploit the correlation between the adjacent bins to fix the permutation for the remaining frequencies.Experimental ... |
