Determination of optimal way for changing signal and noise carrier frequency in detection problems based on the theory of games

There is described a conflicting situation arising during the reception of signal against noise when the carrier frequency of the signal and the noise may change within the given frequency range. In the game model of the situation the possible victory function is selected and its physical sense is examined. The victory function is approximated by the expressions which allow us to find by means of existing methods the optimal strategies and the game worth.
