Listing of Communication in Scripts

This M-File calculates the autocorrelation of a random process by the method of Rader (mentioned e. g. in Karl Kammeyer, "DIGITALE SIGNALVERARBEITUNG : Filterung und Spektralanalyse"): Y=akfrader(X,[M]) X: stationary random process (Vektor) Y: autocorrelation (Vector of length M) M: number for subsequence splitting, Length of resulting autocorrelation function [optional, default is 64].

A number of rules of thumb exist for the advantages of non-coherent averaging, I wanted to see, in a fairly practical way, what the advantage really was. This turned out to be more complex than I thought, because you have to identify and implement separate parts to the equations for the output noise.

This script simulates the Binary Amplitude Shift keying. Since BASK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for 5 bits, so that the results are visible. This is code for BASK only, means it can only modulated two digital states.

This technique takes advantage of the kernel trick that can be used in PCA. This is a tutorial only and is slow for large data sets. In line 30 the kernel can be changed. Any Kernel should do it. Ref : http://www.eecs.berkeley.edu/~wainwrig/sta...kopf_kernel.

Useful for the RF designer, it manipulates the various complex representations of the circuits as multiports, namely transformation from one representation to another and reading/writing to file in industry-standard format it contains stuff written/revised between 1993 and 2003, therefore a quite a few things could be better done today, especially file parsing/writing; however, most of the transformations are singularity-protected and I think this toolbox can really help one to get insight when working at high frequencies.

DSP education is being challenged to move students beyond theory to DSP implementations. Dr. Mark A. Yoder, professor of electrical and computer engineering at Rose-Hulman Institute of Technology, addresses this need with multimedia signal processing labs in which students use Simulink and Real-Time Workshop to design and implement programs onto DSP chips that synthesize music in real time.

Mean or standard deviation are usually computed for whole part of the analysed signal. However, sometimes we would like to know how this quantities are changing in the data flow. MEANSTDF compute the expected mean and standard deviation values using user defined window for every data position.

According to shannon theory it is possible to reconstruct a band limited signal from its Fourier components provided it is sampled sufficiently...just to demonstrate this, posting a small example based on that.

The Empirical Mode Decomposition is a technique to decompose a given signal into a set of elemental signals called Intrinsic Mode Functions. The Empirical Mode Decomposition is the base of the so-called 'Hilbert-Huang Transform' that comprises also a Hilbert Spectral Analysis and an instantaneous frequency computation.

This basic model shows you how to acquire live data from an Agilent oscilloscope into Simulink. This model was developed for the Agilent 6000 series oscilloscope but may work with other Agilent scopes with little or no modifications. I welcome submission reviews below to let us know whether you got it working with your specific Agilent scope.

This file improves on the functionality of interp1 and allows the resampling of more complex data. Measurements can be taken completely arbitrarilly and need not be unique. Target uses are for data which is sampled against a signal that may contain noise or where there may be several measurements at each given point.
