某公司安装了电子门，要设计门禁系统： 公司的雇员可以凭借密码、胸卡或指纹进入公司 计算机根据雇员的验证方式对其身份进行验证 管理员在监控室可以通过按钮直接开启电子门 访客可以按门铃请求进入，由管理员为其放行 管理员可以为新职员设置密码 (A company to install an electronic gate, to design access control systems: the company' s employees can rely on passwords, badges or finger into the company computer, authentication of the employee to verify their identity can be an administrator in the control room directly through the button to open electronic gates that visitors can rang the doorbell of the request to enter an administrator can be released by the administrator of its staff to set a password for the new)

： ：： ：针对传统麦克风阵列声源定位算法抗噪声及混响能力不强的问题，提出一种基于最小熵值和随机域压缩的麦克风阵列声源定位算 法。利用最小熵值方法对麦克风阵列进行时延估计，并与随机域压缩方法相结合，对声源进行空间搜索。仿真实验结果表明，该算法在定 位精度、抗噪声及抗混响能力方面均优于广义互相关相位变换算法。(Sound source localization algorithm based on minimum entropy microphone array)
