Abstract Interference rejection in a wireless communication system involves determining a complement spatial-temporal signal subspace that is complement to a spatial-temporal signal subspace of an interference signal included in a received signal. The received signal is projected onto the complement spatial-temporal signal subspace, whereby the interference signal included in the received signal is reduced. Determining the complement spatial-temporal signal subspace can include estimating the interference signal; determining a Block Yule-Walker matrix for the estimated interference signal; and determining the complement spatial-temporal signal subspace from the Block Yule-Walker matrix.
