Comprehensive performance analysis of power-inversion algorithm used in GPS adaptive arrays

The problem of protecting the GPS signal from interference is addressed. The power inversion algorithm (PI) used in GPS adaptive null-steering arrays is detailed presented. The algorithm based on LCMV rule, which simple to implement and not computationally intensive, is useful because it does not require detailed knowledge about desired-signal structure or arrival angle. In this paper, Comprehensive characteristics attainable with a PI array are derived by sufficient analysis in theory, further more, well experimental results show the fine validity of the proposed characteristics.
