摘要：

A new approach based on the constant modulus (CR I) criterion is proposed to separate instantaneous linear mixtures of signals using a Linear memoryless multiple input multiple output (MIMO) system, Even though a nonconvex cost function is minimized, analyses show that minima correspond to parameter settings where perfect separation is achieved.
