چکیده

The aim of this paper is to provide performance analysis of a deterministic method proposed recently for blind identication of linear time-invariant channels, in the presence of additive noise, for block transmission systems using redundant precoding. Robustness of the blind estimation method is also analyzed in the presence of slow channel variations arising due to Doppler shifts or due to phase noise at the transmit/receive oscillators. The theoretical analysis is validated by simulations.

Redundant filterbank precoders and equalizers. II. Blind channel estimation, synchronization, and direct equalization

Transmitter redundancy introduced using finite impulse response (FIR) filterbank precoders offers a unifying framework for singleand multiuser transmissions. With minimal rate reduction, FIR filterbank transmitters with trailing zeros allow for perfect (in the absence of noise) equalization of FIR channels with FIR zero-forcing equalizer filterbanks, irrespective of the input color and the chan...

Filterbank Precoders for Blind Equalization: Polynomial Ambiguity Resistant Precoders (PARP)

Filterbank precoding in the intersymbol interference (ISI) mitigation has recently attracted much attention. Two main areas of such research have been explored. One of them is on filterbank precoding when the ISI channel is known to both the transmitter and the receiver, while the other is on filterbank precoding when the ISI channel is not known to the transmitter or the receiver. This paper i...

Subspace-based (semi-) blind channel estimation for block precoded space-time OFDM

Space time coding has by now been well documented as an attractive means of achieving high data rate transmissions with diversity and coding gains, provided that the underlying propagation channels can be accounted for. In this paper, we rely on redundant linear precoding to develop a (semi-)blind channel estimation algorithm for space time (ST) orthogonal frequency division multiplexing (OFDM)...
