Co-frequency and co-time full duplex(CCFD) is an attractive technology for the future wireless communication because of its high spectral efficiency.However,applications of CCFD to mobile network can suffer from strong base station to base station(B2B)interference.In this paper,the authors proposed a design that uses centralized base station(BS)transmit antenna and distributed BS receive antennas,each of which consists of an antennary to perform beamforming that can nullify the B2 B interference.In addition,we proposed a combination algorithm that uses the zero forcing method to cascade the recursive least square(RLS) method for reducing the necessary number of the bits taken to the digital processor.This enables the faster convergence and,thus,allows the transmission of more information bits,compared to the conventional method,for mobile communication.The simulation results confirm this approach for practical application.

在教学中,当教师拿着课前精心准备的教案与学生对话时,在不经意间,学生往往会跳出我们预先设定的框架,令教师措手不及,让预先设置的任务没办法完成。这时,教师如果能将“预设”与“生成”巧妙结合,课堂也许就会在精密中蕴涵细腻,在端庄中焕发灵性。  在教学《幸福是什么》时,教师让学生谈谈不同职业的人对幸福的不同理解。一学生站起来,问道:“老师,你觉得幸福吗?”我一时愣住了,这一问题是我课前没有想到的。再说了

我原先带班的教室在三楼,窗外不远处有一片海,蓝蓝的,不见边际。天气晴好时,还能看到朵朵的浪花,隐隐听到哗哗的声音,十分惬意。今年,我接手了一个新的班级,教室从三楼换到一楼,而这里的窗外是一堵厚重高耸的院墙,墙顶上长着几棵稀疏却也嫩绿的小草,显得很有生机。  当我第一次走进这个陌生的环境时,迎接我的一幕是垃圾遍地。班上已乱成一锅粥,有大声说笑的,有追逐打闹的,有玩耍嬉戏的。他们瞟了我一眼,没在意,依
