Listing of Communication in Scripts

This very simple m-function computes cross spectrum, coherence and phase at the same time. The input parameters are equivalent to pwelch.n or csd.m in MATLAB and use csd.m in the singal toolbox. It's very simple but useful for engineers..

Let us assume the signal model: Y(k)=HX(k)+B(k) This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly greater than the number of sources.

MATLABs most commonly used 3-d plotting tools surf and mesh require rectangular grids to plot in 3-d, not x,y,z triples. This function converts arrays of x,y,z triples into rectangular grids to use with surf, mesh, etc. common usage: [x y z] = xyzplotter(xin,yin,zin) xin,yin,zin are n x 1 arrays that define your surface.

This example demonstrates how you can use MATLAB to develop an application that both collects data from an oscilloscope and performs mathematical calculations and visualization on the data. Combining MATLAB with your oscilloscope transforms the scope into a complete test bench station for data collection and data analysis.

This Function HistConnect will make a smooth histogram for a signal or image consisting of a few samples. The function assumes correlation between the samples, and implicitly generates new linear-interpolated samples between the originate samples. Thus makes the assumption of continuity between samples and low-frequency signal.

Compute the discrete Fourier transform at specified frequencies, not using fft. Why one may need this? (1) MATLAB fft function computes the amplitude of signals only (no phase). (2) Once having the recorded time-series data, one often uses fft to do the spectral analysis.

- picks reasonable limits and ticks - uses latex for pretty fractions if necessary - replaces old labels produced by previous calls - does NOT autocorrect on zoom/pan/resize algorithm: - choose limits as smallest n such that pi/n < x_data_range - optional: increase n to next smallest "round" number - "round" means "power of 2" right now; could be a*b^n with a<b, 2^a*3^b, etc - choose step size as smallest d that ensures at least L tick marks I'm sure there are plenty of bugs.

This entry provides functions and examples allowing you to create Simulink.TsArray and Simulink.TimeSeries objects from a script or the MATLAB command line. A Simulink.TsArray object can be used as input data for a bus signal input in Simulink. Note: These functions contain **UNDOCUMENTED** functionality that is subject to change in a future MathWorks release.

When audio or video is transmitted over an Ethernet network, the data is usually transmitted in bursts of packets with long idle times in between bursts. SimEvents is a good tool for modeling those types of sources and studying the effects of queue size and server times on the audio or video transmission.

SMOOTHN provides a fast, unsupervised and robust discretized spline smoother for data of any dimension. SMOOTHN(Y) automatically smoothes the uniformly-sampled array Y. Y can be any N-D noisy array (time series, images, 3D data,...). SMOOTHN can deal with missing (NaN) values (see screenshot, top panels).

Implements soft-decision Viterbi decoding for a rate 3/4 code over an AWGN channel using Simulink. The Viterbi decoder block from the Communications Blockset is enhanced to optimally support punctured codes. The attached BERTool session file compares the BER performance as the number of bits are varied for the soft decision with the performance for unquantized inputs.
