mini2440上qtopia应用程序开发步骤(arm-qtopia版本)(mini2440 steps on the qtopia application development (arm-qtopia version))

MATLAB实现了HARQ重传，分析误码率和信噪比间的关系，并可以修改最大重传次数(MATLAB implements the retransmission of HARQ, analyzes the relationship between the bit error rate and the signal to noise ratio, and can modify the maximum retransmission times.)

MATLAB code for power allocation in V2X networks using SDR and beamforming

本文分析了多级维纳滤波器的特性，在加性噪声和二维天线阵列如均匀圆阵、均匀面阵、十字阵等条件和背景下，对信源个数和信源参数估计问题进行了研究，提出了基于多级维纳滤波器前向分解特性的快速参数估计方法，同时提出了基于多级维纳滤波器的二维ESPRIT参数估计方法，该类方法无需协方差矩阵的估计运算及分解运算，计算复杂度较低。另外，还提出了对信源个数的估计算法。(This paper analyzes the characteristics of multistage Wiener filter, in the additive noise and the two-dimensional antenna array such as a uniform circular array, the uniform array, cross array conditions and background, the source number and source parameter estimation problem undertook study, put forward based on Multistage Wiener filter prior to the decomposition characteristics of fast parameter estimation method, at the same time based on Multistage Wiener filter 2D ESPRIT parameter estimation method, the method does not need to estimate of covariance matrix calculation and decomposition, relatively low computational complexity. In addition, also put forward for source number estimation algorithm.)

用matlab仿真零均值高斯白噪声通过低通带通滤波器前后特性，程序完善，结果与理论值非常接近(The zero mean white Gauss noise is simulated by MATLAB, and the program is perfect through the low pass bandpass filter. The result is very close to the theoretical value.)

使用 VC++ 调用微软蓝牙 API 函数的示例代码。可以使用 VC++6.0 至 VC++2010 编译代码。(Using VC++ call Microsoft Bluetooth API sample code. You can use VC++6.0 to VC++2010 compiled code.)

数字信号处理相关实验，包括求系统零极点，快速傅里叶变换，长序列卷积，FIR，IIR等。(Digital signal processing related experiments, including zero and pole of the system, fast Fourier transform, long sequence convolution, FIR, IIR and so on)

说明：  仿真相干光通信系统，包含各种损伤和均衡算法(the model of coherent optical fiber channel)

本人用石川法求齿轮的啮合刚度，完整版的程序，里面可以运行啮合刚度图(Meshing Stiffness of Gears Calculated by Ishikawa Method)
