Abstract: In this paper two new lower bounds of undetected error probability for (n, k) linear block codes in GF(q) are obtained. The Wolf and his c<> operative authors' results are improved to a certain extent. Because new lower bounds are not relative to the weight structure of the codes, it is easy to estimate undetected error probability of various linear block codes.

Key words: digital communication, information theory, error correcting code, undetected error probabilUy, lower bound
