- Abstract:
- This paper studies the modulation of MPSK based on OFDM channel system. by deduction and a-nalysis of the second-order cumulants and the fourth-order cumulants of MPSK signal An innovative feature todistinguish the modulation order of the MPSK is presented. This feature,due to its simple extracted approachand easy realization, can efficiently achieve the goal of modulation classification. The paper gives transmissionbit error rate and the modulation recognition rate of OFDM system,and gives a comparison simulation of theMPSK recognition rate between the modulation algorithm based on high-order cumulants and spectrum line fea-ture. The result shows that the advantage of high-order cumulants analysis.
