MATLAB actually has a built-in clustering function called kmeans. Assuming you can reshape your data to match the format expected by kmeans, you're ready to go.

Considering that the clusters represent decision region for each sent symbol, how can i determine the decision region, and how can i find the bet error rate for the clusters resulting from the Kmean?

Thank you Kawther Hamad,

Can i consider the originally sent data as a training data and resend data again and consider it and a test data and use them to find the bet error rate?
