Beamformingformovingsourcespeechenhancement
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 .)

一种基于高阶累积量的数字调相信号识别方法
对当前通信信号中常用的数字调相信号BPSK、QPSK、1／4一QPSK、8PSK的调制识别问题，提出了一种基于信号差分高阶累积量的识剐算法。该算法分两个层次进行调制识别，首先利用信号的四阶累积量特征对BPSK、QPSK和{1／4一QPSK、8PSK}信号进行识别，然后再利用信号差分的四阶和八阶累积量特征对1/4-QPSK、8PSK信号进行识别。从理论上分析了的该算法的有效性，并通过计算机仿真验证了算法具有良好的性能。(A recognition algorithm based on differential high-order cumulant is proposed for the modulation recognition problems of BPSK, QPSK, 1/4-QPSK and 8PSK, which are commonly used in current communication signals. The algorithm is divided into two levels for modulation recognition. Firstly, BPSK, QPSK and {1/4-QPSK, 8PSK} signals are identified by using the fourth-order cumulant characteristics of signals, and then 1/4-QPSK and 8PSK signals are identified by using the fourth-order cumulant and eighth-order cumulant characteristics of signal difference. The validity of the algorithm is analyzed theoretically, and the good performance of the algorithm is verified by computer simulation.)
