Computer based exercises for signal processing using matlab 5

The following Matlab project contains the source code and Matlab examples used for computer based exercises for signal processing using matlab 5. Focusing on MATLAB 5, this book includes a collection of computer exercises and projects that helps students understand the principles of signal processing and experience the excitement of applying abstract mathematical concepts to the processing of real signals.

Movable, stretchable zoom box in parent axes controls axes limits in all children axes. in matlab

The following Matlab project contains the source code and Matlab examples used for movable, stretchable zoom box in parent axes controls axes limits in all children axes. . Move this box around to zoom in on or pan across another axes. Similar in functionality to SPTOOL zoom and pan. Ideal for signal processing, large data sets, and time series data.

Bregman cookbook in matlab

The following Matlab project contains the source code and Matlab examples used for bregman cookbook. This toolbox provides functions mainly to solve sparse algorithms (denoising, deconvolution) for signal processing, image processing and 3D datacube processing. It covers Rudin-Osher-Fatemi (ROF) algorithms, Total Variation (TV) deconvolution, framelet/curvelet deconvolution.

Ber curve for bpsk in gaussian environment in matlab

The following Matlab project contains the source code and Matlab examples used for ber curve for bpsk in gaussian environment. Calculate and plot BER curve against SNR for BPSK Modulation in Gaussian Environment. It calculates 100 errors to Calculate BER for every SNR value to ensure better approximation. I hope that this help students of signal processing and communications alot.

Wiener Filter Matlab Code

Wiener filter is a filter used to produce an estimate of a desired or target random process by linear time-invariant filtering an observed noisy process, assuming known stationary signal and noise spectra, and additive noise. The Wiener filter minimizes the mean square error between the estimated random process and the desired process.

K Means Clustering Matlab Code

k-means clustering is a method of vector quantization, originally from signal processing, that is popular for cluster analysis in data mining. k-means clustering aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean, serving as a prototype of the cluster. This results in a partitioning of the data space into Voronoi cells.

Fft Matlab Code

A fast Fourier transform (FFT) is an algorithm to compute the discrete Fourier transform (DFT) and its inverse. Fourier analysis converts time (or space) to frequency and vice versa; an FFT rapidly computes such transformations by factorizing the DFT matrix into a product of sparse (mostly zero) factors.
