Multi-linear subspace estimation and projection for efficient RFI excision in SIMO systems

The paper introduces the multi-linear algebra framework to the radio frequency interference (RFI) excision research by proposing a multi-linear subspace estimation and projection (MLSEP) algorithm for efficient RFI excision in single-input multiple-output (SIMO) systems. Thereafter, the paper compares the MLSEP algorithm with the state-of-the-art projection-based RFI excision algorithms. Eventually, Matlab® Monte-Carlo simulations corroborate that MLSEP outperforms the state-of-the-art projection-based RFI excision algorithms.
