The application of adaptive antenna arrays for GPS is one of the ways in order to achieve a more accurate estimation of user position, as well as signal enhancement and interference cancellation. In fact, adaptive arrays provide an automatic adjustment of the radiation pattern, according to the incident signals and a given adaptation criterion, associated with an efficient signal processing algorithm. Such algorithms are generally based on space-time theory, involving DOA estimation, and impose some a priori knowledge on the number of interference as well as on desired signals.
