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 beamforming for speech enhancement, a constrained subband beamforming algorithm. Its beamformer based on a soft constraints, the aim is to make the beam point to a specific region that is the direction of the sound source. And its core is the first to sound source location, access to location information as accurately as possible, and then construct the conditions of soft constraints for beamforming. And in the process continuously tracking the movement of a sound source. Structure at the binding conditions, need to know the two-dimensional sound source information, that is, with the microphone array the distance and direction angle, the " soft" embodied in the distance and direction angle of the determination are within the scope must be further corrected .)

turbo均衡的一种算法修改的MMSE算法对深刻理解TE很与帮助。(turbo balanced an algorithm modified MMSE algorithm is with a deep understanding of TE help.)

采用滤波器组，将盲分离与声源定位结合在一起。滤波器组中分别进行子带处理，并且在每个子带中进行声源定位，最后综合所有子带估计的方向得到多个声源的方位信息，同时将声源信息作为ICA分析的约束条件，可以在色噪声及多得到更好的盲分离效果。其优势在于用滤波器组进行多次的估计声源方向，再加以合适的权值均衡后即可得到更优的估计。(The use of filters will be blind source separation and sound localization together. Filter group were sub-band treatment, and in each sub-band in Sound Source Localization, and finally all the sub-band is estimated to be more than the direction of sound source location information, as well as sound source information as ICA analysis of the binding conditions, colored noise can be better and many of the blind source separation effect. Its advantage lies in a number of filter banks with estimated sound source direction, coupled with an appropriate balance weights can be obtained after the better estimate.)

重点研究 了低信噪比﹑多径瑞利衰落信道条件下，基于高阶累积量的OFDM信号盲识别技 术。提出了利用奇数阶累积量区分OFDM信号与单载波信号的方法，并对基于三 阶和五阶累积量的算法进行了仿真分析。 (﹑ Focus on the low SNR multipath Rayleigh fading channel conditions, based on cumulant OFDM signal blind identification technology. Made a distinction between the use of odd-order cumulants single-carrier OFDM signal with the signal approach, and based on the cumulative amount of third-order and fifth-order algorithm for the simulation.)
