Sensitivity of L-1 regularization on subspace-based SIMO blind channel identification in sample channel measurements

Abstract

Single Input Multiple Output (SIMO) Blind Channel Identification (BCI) using Subspace-based Methods, notably the Cross-Relations (CR) and Noise-Subspace (SS) Methods, are sensitive to selection of the channel order. Previous work on model order selection shows that at low SNR, accurate selection is not always possible, and in some cases, there is difficulty… (More)
