Patent ID: 7397874

Claim:
A V-BLAST (Vertical Bell Laboratories Space-Time codes) detection method for a MIMO (Multiple Input Multiple Output) system, including: a first detecting step for acquiring in sequence the old detection components ( a ^ M old , a ^ M - 1 old , … ⁢ , a ^ 1 , where ⁢ ⁢ M ⁢ ⁢ is ⁢ ⁢ an ⁢ ⁢ integer ) of a transmitting symbol vector (a) with the optimum ordering-successive interference cancellation detection method; a second detecting step for taking the detection component (â 1 ) with the highest space diversity degree among the old detection components ( a ^ M old , a ^ M - 1 old , … ⁢ , a ^ 1 ) as a first new detection component, and acquiring in sequence other new detection components ( a ^ 2 new , a ^ 3 new , … ⁢ , a ^ M - 1 new , a ^ M new ) of said transmitting symbol vector (a) in an inverse order of optimum detection order with the optimum ordering-successive interference cancellation detection method; an outputting step for outputting said first new detection component (â 1 ) and said other new detection components ( a ^ 2 new , a ^ 3 new , … ⁢ , a ^ M - 1 new , a ^ M new ) as the final detection result.
