Abstract:
A method for detecting soft-decisions in a 2×2 MIMO system includes detecting all candidate symbol vector sets S in which there exist all values of a real part and an imaginary part, and calculating a log-likelihood ratio (LLR) with respect to the candidate symbol vector sets S from LLR ( b k i ) = min s ∈ S ⋂ β i , k - ED ( s ) 2 σ n 2 - min s ∈ S ⋂ β i , k + ED ( s ) 2 σ n 2 .
