Abstract :
This letter concerns the problem of signal cancellation in adaptive array systems, when the jammer power is relatively large, and the jammer is correlated with the desired signal. An LMS algorithm to reduce such signal cancellation is introduced. Its steady-state performance is similar to that of the dither algorithm proposed by Widrow [1], but does not require mechanical motion of the receiver array.
