Abstract :
A new approach to classification of MQAM/MPSK signals in multipath fading environments is presented The proposed approach, in which the two-step equalization strategy and higher-order cumulants based classifier are adopted, can effectively classify the MPSK and high-order QAM signals. The performance of proposed approach is evaluated by the computer simulations, which shows it has better classification ability.
