ABSTRACT:
The present invention discloses a V-BLAST detection method for a MIMO system, including: a first detecting step for acquiring in sequence the old detection components of a transmitting symbol vector with the optimum ordering-successive interference cancellation detection method; a second detecting step for taking the detection component with the highest space diversity degree among the old detection components as a first new lo detection component, and acquiring in sequence the other new detection components of the transmitting symbol vector in an inverse order of the optimum detection order with the optimum ordering-successive interference cancellation detection method; an outputting step for outputting the first new detection component and the other new is detection components as the final detection result. The method according to the invention employs the outer close loop iteration technology to further reduce inter-layer error propagation of V-BLAST. This method has less complexity.
