利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％， 不加入噪声，进一步生成某个特定的中频信号(The baseband signal is generated using Matlab GPS C/A code. (1) generate satellite PRN number " 5" is a set of C/A code (2) loop generates 25 navigation data, GPS time can be filled with a fixed known value (3) generated C/A code spread spectrum signals, each C/A code chip sample data is given 4 (4) a baseband signal using a square wave signal with a level of 0 and a duty cycle of 50 , the noise was not added, and further generates a a specific frequency signal)

说明：  同步电机模型的MATLAB仿真。。本文针对同步电机中具有代表性的凸极机，在忽略了一部分对误差影响较小而使算法复杂度大大增加的因素（如谐波磁势等），对其内部电流、电压、磁通、磁链及转矩的相互关系进行了一系列定量分析，建立了简化的基于abc三相变量上的数学模型，并将其进行派克变换，转换成易于计算机控制的d/q坐标下的模型。(MATLAB simulation of synchronous machine model. . Synchronous motor in this paper, salient pole machine with a representative, in the neglected part of the error is less impact on the complexity of the algorithm greatly increase the leaving of factors (such as the harmonic magnetic potential, etc.), its internal current, voltage, magnetic flux, flux and torque relationship between a series of quantitative analysis, a simplified three-phase abc variables based on the mathematical model, and the Park transformation, into easy-to-computer control of the d/q coordinate model .)

在复杂的电子系统中，影响信号接收的很多噪声为非高斯噪声，这些噪声是没有预料到的，以致破坏了接收机的功能，研究表明：这些噪声可以看成双模噪声，双模噪声从整体上讲属于非高斯噪声。(In complex electronic systems, many of the signal received by a non-Gaussian noise, the noise is not anticipated, resulting in damage to the receiver function, research shows that: the noise can be regarded as dual-mode noise, dual-mode noise As a whole is non-Gaussian noise.)
