Modified channel subspace method for identification of SIMO FIR channels driven by a trailing zero filter bank precoder

摘要

A modification of Moulines' blind second order statistical channel subspace approach (see Moulines, E. et al., IEEE Trans. on Sig. Proc., vol.43, no.2, p.516-25, 1995) is proposed for the identification of single input multiple output finite impulse response channels. The modification exploits the transmitter redundancy introduced by a trailing zero filter bank precoder. The method is shown to be robust to common zeros and channel order over-estimation errors.
