Abstract
Blind channel estimation for periodic sequence DS-CDMA systems can be cast into the framework of `structured' blind estimation of multi-input/multi-output (MIMO) FIR systems, where the structure is imposed by the user's signatures. A possible approach to tackle this problem consists in looking for a structured solution to one of the so-called `blind' MIMO-FIR system identification techniques proposed recently. This is the approach undertaken, among others, by Wang and Poor, who proposed an adaptation of the subspace method originally developed by Moulines et al. for single-input multiple outputs (SIMO) FIR systems, and later extended by Abed-Meraim et al to MIMO-FIR systems. In this contribution, we follow this approach to consider the particular blind forward channel estimation problem, and improve quite significantly the results presented in [16].
