Listing of Communication in Scripts

The k-means algorithm is widely used in a number applications like speech processing and image compression. This script implements the algorithm in a simple but general way. It performs four basic steps. 1. Define k arbitrary prototypes from the data samples.

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.

This function convolves two very large vectors very quickly. Enormous gains in speed are due to the use of two fft's and an ifft. To find out how to use this program, put it in you 'work' folder and type "help fconv"..
