Blind space-time adaptive filtering based on electronically steerable passive array radiator antennas

Abstract

The electronically steerable passive array radiator (ESPAR) antenna is one kind of single port antenna with parasitic elements, and is thus of lower complexity and low cost in the realization of space-time adaptive filtering (STAF). The authors extend the cumulant-based super-exponential algorithm to super-exponential blind adaptive beamforming. We propose blind space-time adaptive filtering based on ESPAR antennas. The blind STAF is performed under the inverse filter criterion, and the higher-order cumulant based blind super-exponential adaptive beamforming algorithm.
