摘要
In this paper we will see that the linearly constrained differential constant modulus (LCDCM) cost criterion is well suited for blind multiuser detection. Unlike the linearly constrained constant modulus (LCCM) cost function, it is not dependent on desired user amplitude to ensure a single optimum point. The global minimum of the LCDCM cost function will be established by proving the Hessian matrix positive definite at the single solution where the gradient function is zero.
