Abstract :
This paper proposes the complex domain solution of the blind decision feedback equalizer (DFE) based on joint entropy maximization (JEM) criterion. For the feedback filter of DFE, a new complex activation function is defined and then the stochastic gradient algorithm of the JEM type is derived. The fact that the JEM cost is a real function of complex quantities suggests the method associated to a least man-square criterion.
