Abstract :
Outputs from linear minimum-variance equalisers have nonzero conditional bias and residual intersymbol interference even at high s.n.r. It is shown that both can be calculated from the covariance of the message estimates produced by the equaliser. The use of the covariance in computing error bounds is also described.
