说明：  CONVERT A MATRIX TO LOWER TRIANGULAR MATRIX

HFSS 带通滤波器 微带结构 (HFSS microstrip structure band-pass filter)

说明：  数字信号的调制识别，提取了信号的时域特征与频域特征。包含神经网络训练。(Modulation recognition of digital signal.The time-domain and frequency-domain features of the signal are extracted. Including neural network training.)

gsm11.11 gsm11.14规范，用于gsm 的开发(gsm11.11 gsm11.14 norms for the development of gsm)

主要用于各种实际中的定位运算，如TDOA等，可以在很短的时间内进行精确定位(It used in positioning calculation of the actual environment,for example ,TDOA.It can know the exact positioning in a short time.)

介绍了三点垂直线阵被动定位的原理. 结合矢量水听器测得的方位角和高低角及到达 阵元间的时延差, 建立了三维坐标下的状态方程和观测方程.运用扩展卡尔曼滤波算法, 研究了该系统的目标运动分析问题. 通过蒙特卡洛模拟仿真试验, 结果表明上述方法具有较高的定位性能,有较强的使用价值. (Introduced three vertical linear array passive location principle of vector hydrophone. Combining the measured azimuth angle and pitch angle and arrival time delay difference between array elements, establish the three-dimensional coordinates of the state equation and observation equation. Using the extended Calman filter algorithm, on the target motion analysis by Monte Carlo simulation. Test, results show that the method has high positioning performance, has the strong use value.)

说明：  OFDM技术 北京邮电大学内部讲义 内部资料(OFDM 北邮内部讲义)

说明：  提供了一个研究NOMA，如何NOMA解决了5G需求、NOMA正在进行的标准化工作以及NOMA与其他应用程序的比较研究像OFDMA这样的OMA方案。我们还展示了NOMA中用户吞吐量的改进在MATLAB仿真的帮助下实现OFDMA。(This paper provides a study of NOMA, how NOMA addresses the 5G requirements, ongoing standardization efforts for NOMA and a comparative study of NOMA with other OMA schemes like OFDMA. We have also demonstrated improvements in the throughput of the users in NOMA as compared to OFDMA with the help of MATLAB simulations.)
