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 .)

OPNET14.5
说明： 近两天由于研发需要OPNET这个仿真软件，同时要求可以支持wimax仿真模型，对该仿真软件的研究还需要继续进行
好不容易在网络上找到了最新版的OPNET 14.5的软件，但是安装的确出现了很大的麻烦，最后通过查阅网络上对之前版本安装的经验解决了安装过程中的问题，因此将这些分享给大家：
(Almost two days because of this R & D needs OPNET simulation software, also required to support wimax simulation model, the simulation software is also the need to continue the network finally found the latest version of the OPNET 14.5 software, but certainly there was an installation much trouble, and finally access to the network through the installation of the experience of the previous version to solve the problems during the installation process, it will share all of these:)
