1.we simulate the principle of K means clustering algorithm in MATLAB. 2. the constellation diagram of receiving QAM signals is compared at different signal-to-noise ratios. 3. equalizing the received constellation using the K means algorithm, comparing the bit error rate of the algorithm and the direct demodulation without using the algorithm.
