1. , a kind of modulation type to received signal carries out the method for blind Detecting, and this method may further comprise the steps:

  • Generate step, it supposes received signal based on described received signal at each generation in two or more supposition modulation types;

    Characterize step, it characterizes the infringement component of respectively supposing received signal by determining respectively to suppose the in-phase component of received signal and the spatial coherence between the quadrature component;

    AndDetect step, it is based on the modulation type that characterizes the described received signal of infringement component detection.
