Abstract :
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
