%X The analysis of correlation matrix of the received signal proves that the energy of narrowband interference is compressed in the low rank subspace, interference subspace, and the energy of DSSS signal and AWGN uniformly distribute. The narrowband interference suppression can be realized by tracking the interference subspace and projecting the received signal vector to the orthogonal subspace of it. The algorithm proposed here is low complexity, numerical stability and better performance than traditional Adaptive Transversal Filter (ATF).
