Abstract

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