Abstract :
The principles of construction of adaptive interference compensators for user radioaccess systems are considered. It is proposed to use the adaptive antenna array in the basic receiving channel, which allows adjusting zero of the radiation pattern in a direction of arrival of a useful signal. The analysis of the efficiency of the adaptive interference compensator with the adaptive basic receiving channel is carried out. It is shown, that the efficiency of such an adaptive compensator is constant at any direction of a signal arrival except when the angles of arrival of the signal and interference concur.
