Robust transmit processing for frequency-selective fading channels with imperfect channel feedback
C Jonietz, WH Gerstacker… - IEEE transactions on …, 2008 - ieeexplore.ieee.org
Reliable channel state information at the transmitter (CSIT) can improve the throughput of
wireless networks significantly. In a realistic scenario, there is a mismatch between the CSIT
and the true channel. The CSIT may be outdated due to channel variations or could be
erroneous due to quantization effects. In this paper, robust transmit beamforming (rBF) and
the combination of time-reversal space-time block codes (TR-STBCs) with rBF, both
optimized for transmission over frequency-selective fading channels with decision-feedback …

Robust transmit beamforming for frequency-selective fading channels with imperfect channel feedback
C Jonietz, WH Gerstacker… - IEEE GLOBECOM 2007 …, 2007 - ieeexplore.ieee.org
In this paper, robust transmit beamforming (BF) for transmission over frequency-selective
fading channels, taking into account the availability of imperfect channel state information at
the transmitter (CSIT), is considered. In a realistic scenario, the CSIT differs from the true
channel. The CSIT may be outdated due to channel variations or could be erroneous due to
quantization effects and/or transmission errors. Transmit BF with reliable CSIT can improve
the system performance significantly. On the other hand, pure space-time coding …
