- 争对移动声源采用波束形成进行语音增强,提出一种约束子带波束形成算法。其波束形成器基于一个软约束,其目的是要使波束指向特定的区域即声源方向。而其核心在于首先要进行声源定位,获得尽量准确的方位信息,然后构造软约束条件,用于波束形成。且在此过程中不断跟踪声源的移动情况。在构造的约束条件中,需要知道声源的二维信息,即与麦克风阵列的距离和方向角,“软”体现在对距离和方向角的确定都是在一定范围内的,有待进一步更正。-Between the mobile sound source using beamform

- 为虚拟管家系统设计一个麦克风阵列接口,该接口用于接收语音信号作为命令,由麦克风接收识别后用来控制虚拟管家,进而控制各种家用电器工作。当用户移动时,该接口可以跟踪定位用户(此应用中只需知道用户方向角,也是一维定位),即可随时响应用户的控制命令-Housekeeper system for the design of a virtual microphone array interface, the interface for receiving voice signal as a command,

- 基于互相关函数,采用求和广义互相关函数(summed-GCC)法用于机器人系统平台。由于采用不同的映射函数(mapping functions),GCC法在该平台下,只需三个麦克风即可进行三维定位,突破了基于TDOA法进行三维声源定位最少需4个麦克风的限制-Based on cross-correlation function, using generalized cross-correlation function sum (summed-GCC) method for the robot s
