Using unscented transform as alternative to Monte Carlo in bit error rate calculations

The unscented transform (UT) is applied to the calculation of bit error rates of noisy communication channels. The UT is faster than and as accurate as the Monte Carlo method. The technique was successfully applied to several modulation schemes with different noise statistics. The UT has also the advantage of being completely defined by the moments of the random process, instead of demanding full knowledge of the probability distribution.
