The performance of multiple-input-multiple-output (MIMO) systems over flat fading channels by calculating the Union Bound (UB) was analyzed. Based on the original idea of Verdu’s theorem, a new tighter UB by excluding the redundant code-matrices is introduced. The new tighter bound is calculated by the summation of the Pairwise Error Probabilities (PEPs) of code-matrices that belong to an irreducible set.
