%X Dealing with the adaptive nulling of the array radiation pattern, two strategies are investigated in this report. The first one is aimed at maximizing the signal-to-noise-plus-interference ratio whereas the second one is aimed at minimizing the total power received at the output of the array. The performance analysis is proposed in correspondence with a time-varying interference scenario. %D 2014 %A L. Poli %A P. Rocca %A M. Salucci %A A.
