We investigate analytically and by link level simulations the irreducible error, introduced by the time dispersion of the radio channel for multiple-input multiple-output (MIMO) systems with flat fading detection algorithms. Using an adequate synchronisation method, the error floor is determined only by the intersymbol interference, for which a formula is derived. The maximal data rate is not only determined by the value of this interference, but also by the modulation scheme, antenna configuration and channel condition.
