Adaptive array behavior with periodic envelope modulated interference

Abstract

A method is presented for determining the effects of envelope probability more than CW interference for certain choices modulated interference on a least mean square (LMS) adaptive of the signal parameters. The behavior of an LMS array has also been array. The interference is assumed to have periodic envelope des bedafor lesi and, suprss cer, modulation with a bandwidth that is small compared with the de moduled( BAM) intererencersigna carrier frequency. For such interference, the method allows one to specialmd was studied ece it calculate the periodic steady-state behavior of the array weights and results in a differential equation for the array weights that the resulting array performance.As an example, we compute the effects of an ordinary amplitude lead to an intractable mathematical problem.) For modulated (AM) interference signal on the array. It is shown that DSBSC-AM interference, the array weights satisfy a such interference causes the array to modulate the desired signal vector differential equation with properties similar to the envelope but not its phase. With a differential phase-shift-keyed classical Mathieu equation [4]. By using an approach (DPSK) desired signal, AM interference is found to have about the similar to the classical technique, it is possible to obtain same effect on bit error probability as CW interference.
