  • identify
    说明:  通信信号的调制信息包含在信号的瞬时幅度、相位、频率的变化之中,不同的信号其频谱也呈现不同的特征,通过提取瞬时幅度、相位、频率以及频谱的参数统计特征,可以识别不同的通信信号。通常是利用对瞬时幅度、瞬时相位,瞬时频率和信号功率谱进行某种变换而得到可以明显区分各种信号的特征参数。(Communication signal modulation information is contained in the signal instantaneous amplitude, phase, frequency changes, the spectrum of different signals also show different characteristics, by extracting the instantaneous amplitude, phase, frequency and statistical characteristics of the parameters of the spectrum, you can identify different communication signals. Usually by the use of instantaneous amplitude, instantaneous phase, instantaneous frequency and signal power spectrum a transformation which can be clearly distinguished by the characteristic parameters of various signals.)

  • dubsi10-2
    飞机仿真软件包dubsi10-2,可以与FDC tool(本站已有)一起使用的matlab/simulink仿真软件,主要对飞机的滚转姿态控制进行仿真研究,内有丰富的案例。(The Dutchroll Blockset for Simulink, DUBSI, is a stand-alone version of the blocklibrary BLOCKLIB_MISC in version 2.0 (or later) of the Flight Dynamics and Control (FDC) Toolbox, which is currently under development. It contains a number of general-purpose Simulink blocks, which can be used for more applications than flight dynamics research only. Both the FDC toolbox and the DUBSI blockset are copyrighted by M.O. Rauw see COPYING.TXT for more details. )

    Blind Source Separation (BSS) is a statistical approach to separate individual signals from an observed mixture of a group of signals. BSS relies on only very weak assumptions on the signals and the mixing process and this blindness enables the technique to be used in a wide variety of situations.
