FIELD: wireless communication systems.
SUBSTANCE: the wireless communication device signal using for the purpose the unit (36) of coarse removal of the direct component, which removes the relatively high direct components, and the circuit (42) of fine removal of the direct component, which removes the residual components of it. The unit (36) of coarse removal of the direct component may be realized on receiver (22), and the circuit (42) of fine removal of the direct component may be realized on modem (26). Besides, circuit (44) of coarse estimation of the direct component realized in modem (26) may be connected to unit (36) of coarse removal of the direct component for renewal of the values of shift of the direct component stored in unit (36) of coarse removal of the direct component. Due to the fact that the values of coarse estimations of shift of the direct component are stored locally, in the receiver, removal of the direct component may be attained very quickly.
EFFECT: accelerated removal.
