| 摘 要： | 在麦克风阵列信号处理中,通常假定信号源发出的信号经过传播到达不同麦克风阵元时,信号满足平面波传播模型.在此模型基础上,为解决基于麦克风阵列语音增强系统中方位角的估计问题,提出了一种基于Capton最小功率估计的方位角估计算法.仿真结果表明与传统的波束形成算法比较,该算法具有较高的方位角分辨率.

| Abstract: | In microphone array signals processing system,the signals from the source arriving different microphones normally are assumed to fit to plane wave transmitting models.On the basis of this model,a direction of arrival estimation algorithm is proposed based on minimum power estimation to solve the problem of estimating the direction of arrival in the microphone array speech enhancement system.The simulation shows that comparing with traditional beamforming algorithm,the algorithm has better direction of arrival estimation result. |
