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..

The GMM returns the cluster centroid and cluster variances for a family of points if the number of clusters are predefined. The centroid and variance can then be passed to a Gaussian pdf to compute the similarity of a input query point with reference to given cluster.

The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected.

A signal object (an object of class "signal") is a set of data in an one dimensional array, combined with information about its sample rate, starting time and other useful infos. A number of methods makes it easy to generate and modify signals. "signal" is used and tested for considerable time in the aim-mat project.

function y = getiq(x,freq) this takes in the frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q - this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spot OR function y = getiq(data,freq,fc) this takes in frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q based around a center frequency FC this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spot.
