An Efficient and Simple Method of MPSK Modulation Classification
Abstract:This paper reports on a novel method that analyses signals’ Mth power spectrum to classify the modulation type of MPSK signals without carrier and symbol synchronization. Whether signals through the filter or not makes no difference to this method and the multi-path effect has less influence on it. Simulations show that the correct recognition rate up to 99% for SNR >-1dB.

Introduction
The Software Radio (SR) approach leads to the definition of a new generation of radio equipment, munication functions are pletely defined by means of software modules. The main e of the deployment of this technology is the great flexibility of the radio interface. As a matter of fact munication standards can be easily reconfigured by simply replacing the corresponding software modules.
The term Software Radio (SR) refers to an emergent approach in the definition munication transceivers. An ideal SR transceiver can be viewed as a generic putational device wired to a minimal Radio Frequency (RF) front end. The programmable device performs most of the air-interface functions (covering physical and data-link layers up to work layer) in the digital domain by means of software-ponents.
In order to resolve the problem of inter-symbol inter
