It is well known that nonorthogonal quantum states cannot be reliably distinguished; however, for a number of sets of quantum states, the operation of unambiguous discrimination is possible, which either provides full information or yields an inconclusive result. In this paper, a generalization of such a transformation is constructed that has an increased success probability and makes the states more distinguishable. It is shown that after this transformation the states can be reliably distinguished without loss of the total success probability.
