Simulation

- K means algorithm is performed with different initial centroids in order to get the best clustering. - The total cost is calculated by summing the distance of each point to its cluster centre and then summing over all the clusters.Based on the minimum overall cost achieved during each iteration of iterKMeans the pixel assignment to their respective clusters are made and final compressed image is obtained. This algorithm will run slower as the number of clusters , size of the image and number of iterations increase.

This code is used in the course Digital Communications. It simulates 16QAM mode with different SNRs.

This code generate LFM chirp with any length, cycles, delays, and phase offsets. It also ensure continous phase change from one pulse to the other.
