Overall flow chart of FIR filter design This design uses fir filter to filter the speech signal. This simulation design uses matlab as the simulation platform and the signal of matlab as the original speech signal to simulate the filter. The flow chart is shown as follows: General design flow chart The first thing to design is the fir filter. ...

Grey Wolf Optimizer is inspired by the official account of Seyedali Mirjalili, and a meta heuristic algorithm was proposed in 2014. It mainly simulates the search for prey, encircling prey and attacking prey. After the source code pays attention to the public number, it returns to "wolf" or "GWO" to obtain. inspire Gray wo ...

Moving target location algorithm Detect the target in real time and locate the target in real time. 1. Computer simulation modeling of moving target Assuming that the target moves in a uniform straight line and the position of the ith observation station is (x,y), the target motion model can be written as follows: Of which: Note: ...

1, Introduction 1 overview of genetic algorithm Genetic Algorithm (GA) is a part of evolutionary computation. It is a computational model simulating Darwin's genetic selection and natural elimination of biological evolution process. It is a method to search the optimal solution by simulating the natural evolution process. The algorithm is simpl ...

Block transform coding refers to dividing an image into several blocks, mapping each block to another value domain after mathematical conversion, and then coding. It belongs to a kind of transform coding. Because it is often used with quantization, it belongs to lossy data compression. It includes the following forms: DFT transform, DCT transf ...

Matlab has great advantages in data analysis when processing images. Because other programming languages, such as C + +, are generally used when docking with enterprises, Matlab functions can be compiled into dll files and called in C + +. There will be many errors when using it for the first time, and many errors can not be modified by the pro ...

Radar target echo Firstly, the composition and structure of radar target echo are introduced, and then the students have an in-depth understanding of the generation of target echo through code. The echo received by radar can be forward scattering or backward scattering. Backscattering is usually unique to bistatic radar. The signal receiv ...

1, Introduction to image denoising and filtering 1 image denoising 1.1 definition of image noise Noise is an important factor that interferes with the visual effect of image. Image denoising refers to the process of reducing noise in image. There are three kinds of noise classification: additive noise, multiplicative noise and quantization noi ...

Pulse compression / matched filter is one of the most basic operations of radar signal processing. This paper deduces the basic principle of matched filter in detail, and gives the simulation program of matlab. Because there are too many formulas, we share them here in the form of screenshots. If you need word or pdf, you can leave a message o ...

Recently, the class often needs interpolation and fitting. I think I need to summarize the tools used. I mainly use three ways to realize them. matlab 1. matlab toolbox is preferred Give the prepared data to the variables in advance (I don't remember what it should be called here, but put down my data here) x = [760,2240,3480,3805,4720,5960 ...
