Summary: 
In this paper, we introduce, new methods to reduce the complexity of the detection in virtual layered space-time receivers in multiple-input multiple-output (MIMO) systems. Computer simulations indicate that the proposed method can be used to reduce the complexity of detection to approximately 20% in [84] (the transmitter is equipped with 8 antennas and the receiver is equipped with 4 antennas) systems and 40% in [42] systems.
