只使用待测用户的观测数据，不需要其他用户（干扰用户）信息就可以抵消多址干扰进行检测的自适应检测器称为盲自适应多用户检测器，常简称为盲多用户检测。用LMS算法更新检测器系数时即为盲自适应多用户检测的LMS算法(Use only tested the user' s observations, no other user (interference user) information to be offset by multiple access interference detection and adaptive detector known as the blind adaptive multiuser detector, usually referred to as the blind multiuser detection. Detector with LMS coefficient update algorithm when it is blind LMS adaptive multiuser detection algorithm)

matlab实现8PSK TCM网格编码调制，包含维特比译码和与未编码的QPSK误码性能比较(matlab implementation of TCM trellis coded modulation 8PSK, including Viterbi decoding and uncoded QPSK BER performance)

在永磁同步电机的运动控制系统中采用直接转矩控制策略，其性能的优劣程度取决于磁链和电磁转矩的控制情况，因此很有必要进一步的研究控制系统转矩和磁链的性能。(Permanent magnet synchronous motor is widely used in the field of speed control systems because of its various high performance,such as its small volume, high efficiency, reliable work performance, and the advantage of being able to adapt to harsh environment.Direct torque control technology regards the induction motor as the research object , because its idea is novel , its architecture is simple and it has excellent static and dynamic performance of the system , so this technology has received extensive attention.This paper focuses on the surface mounted permanent magnet synchronous motor, and the main work is as follows at direct torque control system.)

说明：  挠性转子的平衡原理是建立在弹性轴（梁）横向振动理论的基础上，其动平衡原理为：挠性转子在任意转速下回转时所呈现的动挠度曲线，是无穷多阶振型组成的空间曲线，其前三阶振型是主要成分，振幅较大，其他高阶振型成分振幅很小，可以忽略不计。(Flexible rotor balancing principle is based on the elastic axis (beam) on the basis of transverse vibration theory, the balancing principle is: flexible rotor turning at any speed when the deflection curve presented is composed of infinite number of vibration modes space curve, the first three modes is the main component, the larger the amplitude, the amplitude of the other components of higher modes is very small, can be ignored.)
