Abstract

In this paper,we prove that oversampling the output of IIR channels can be transformed into a single input multiple output (SIMO) model,and the subchannels have the same AR coefficients.According to this model,a blind identification method is proposed based on subspace.The MA coefficients of the subchannels can be identified by using subspace decomposition.The AR coefficients can be resolved from Yule-Walker equation.

Key words

oversampling / SIMO / subspace decomposition
