Because traditional eigen-subspace projection (ESP) methods cannot cancel the main lobe interference, an improved ESP algorithm and an orthogonal array of antenna are proposed to overcome this problem. Based on the orthogonal antenna array, the proposed algorithm combines ESP with ICA and signal blocking methods, which implements the extraction of part of the main lobe interference and optimized the estimation of the interference subspace. Both simulation and experiment results show that the improved ESP algorithm provides robust cancellation capability of main lobe and sidelobe interference for super low frequency (SLF) communication.
