It is shown in the article, that at a necessity conducting of analytical researches of the wireless systems it is possible to use approximation of integral of errors, as she does not worsen the got results and simplifies an analysis. Quantitative comparisons of probability of appearance of errors of bits are conducted for the different types of multidimensional modulations (M-ASK, MPSK, M-QAM). Areas are shown where advantages of M-PSK and M-QAM are comparatively with M-ASK.
