[matlab例程] basic_iterative
说明:This is a matlab program using the most-likelihood method to estimate the frequency of a sinusoid wave. Also, a basic filter is provided to check the benefit from using that. The result show that ML method reacches CRB at normal SNR.<LionTheGreat> 在 2025-09-14 上传 | 大小:1kb | 下载:0
[matlab例程] basic_ESPRIT
说明:This a matlab program using ESPRIT method the estimate the frequency of a sinusoid wave. It is shown that this method finds out exactly the fact when there is no noise, but works worse than ML in accuracy in noise.-This is a matlab program using ESPR<LionTheGreat> 在 2025-09-14 上传 | 大小:1kb | 下载:0
[matlab例程] ex01
说明:此程序给出由三个不同频率的正弦所组成信号的联合时-频分布。该图是三维图形的二维投影,在该图中,一个轴是时间,一个轴是频率。由该图可清楚地看出信号的时间-频率关系。-This program shows three different frequency sinusoidal signal composed of joint time- frequency distribution. The plan is two-dimensional projection three-dimensional<yangan> 在 2025-09-14 上传 | 大小:1kb | 下载:0
[matlab例程] changing-freq
说明:This a matlab program using most liklihood method to estimate the frequency of a sinusoid wave. Furthermore, this provides a monte-carlo test to check for mean error and error variance of this method, which is to be compared with the CRB.-This is a m<LionTheGreat> 在 2025-09-14 上传 | 大小:2kb | 下载:0

[matlab例程] gn1110
说明:加速度到位置的二次积分模型,采用simulink编写,带加速度噪声,可用于简单的导航位置与实际位置仿真-Acceleration to the position of the double integration model, using simulink writing, with acceleration noise can be used for simple simulation of the actual location of the navigation position<alphaday> 在 2025-09-14 上传 | 大小:4kb | 下载:0
[matlab例程] ESPRIT_monte_carlo
说明:This a matlab program using ESPRIT method to estimate the frequency of a sinusoid wave. Futhermore, a monte carlo test is provided to check for the mean error and error variance, comparing to the CRB.<LionTheGreat> 在 2025-09-14 上传 | 大小:1kb | 下载:0
[matlab例程] ex02
说明:此程序给出信号的多分辨率分析(Multiresolution Analysis),即信号的多分辨率分解(Multiresolution Decomposition)方法及应用。该程序是一个多抽样率系统(Multirate System)举例,用M个的滤波器,将信号的频谱等分成M部分,使所得抽样频率降为1/M,然后再依据它们的“重要性”给一不同的bit数,那么所传输的bit流必然会进一步下降,起到压缩带宽的作用。-This program gives the signal of the multi<yangan> 在 2025-09-14 上传 | 大小:1kb | 下载:0
