CDMA2000调制扩频与解调解扩的MATLAB仿真(CDMA2000 spread spectrum modulation and de conciliation spread MATLAB simulation)

使用传统的几种算法来形成自适应波束，包括最大信噪比准则（MSNR），线性约束最小方差（LCMV）和最小均方误差准则（MMSE）等。(The traditional algorithms are used to form adaptive beams, including maximum signal-to-noise ratio (MSNR), linear constrained minimum variance (LCMV), and minimum mean square error criterion (MMSE).)

码分多址(CDMA)技术作为第三代移动通信系统的核心技术，具有容量大、抗干扰能力强等优点。然而,传统的CDMA系统属于窄带扩频系统,它的数据速率比较低,不能胜任新一代移动通信系统 （beyond 3G）高速数据通信的需要。而多载波传输技术－正交频分复用（OFDM），作为后三代移动通信的核心技术，则具有高数据速率传输的特点。(Code Division Multiple Access (CDMA) technology as the third generation mobile communication system' s core technology, high capacity, anti-interference ability and so on. However, the traditional narrow-band CDMA system is spread spectrum system, and its relatively low data rate, can not do next-generation mobile communication systems (beyond 3G) high speed data communication needs. The multi-carrier transmission technology- orthogonal frequency division multiplexing (OFDM), after three generations of mobile communications as a core technology, the high data rate transmission characteristics.)

针对频率周期振荡的振动系统讨论自适应控制问题,在频率跟踪的基础上对频率变化的振动响应进行控 制,给出相应的估计、滤波与控制方法。首先在子空间辨识原理的基础上,通过测量信号自相关序列的递推运算获得信号 频率 然后根据估计频率实时调整带通滤波器的中心频率,使其跟踪信号频率,实现信号分量的跟踪滤波 最后在LMS方 法的基础上构造对信号分量进行控制的自适应控制器。(The adaptive vibration control of systems excited by forces of periodically varying frequencieswas dis- cussed. The presented adaptive controlwas realized on the basis of tracking of time-varying frequencies and amethod for online frequency estimation, filtering and controlwas proposed. Based on the principle of subspace identification, the time-varying frequencieswere estimated from the recursively computed autocorrelation ofmeasured signals. )
