In this paper we present a relationship between supervised (MMSE) and unsupervised criteria for minimum bit error rate (BER) filtering. A criterion based on the probability density function (pdf) estimation which has an information theoretical approach is used to link the MMSE criterion and the maximum a posteriori one in order to obtain a linear filter that minimizes the BER. An analytical relationship among those three criteria is presented and analyzed showing the limits imposed to achieve minimum BER without training sequences when the pdf estimation-based criterion is considered.
