… This paper studies the impact of imperfect CSI on a multiple-input multiple-output (… imperfect
at the transmitter but perfect at the receiver, whereas this is not true for the case of imperfect …

… The numerical results verify the fact that it is always better to exploit the channel knowledge
at the transmitter. When the channel uncertainty is very small, one may use the beamforming …

… The question concerning the effect of imperfect channel knowledge on mutual information in
… multiple-access capacity region in memoryless channels can be attained using interference …

… In contrast to most of the existing literature, we have investigated the impact of imperfect
channel knowledge of the primary–secondary link on the SU mean capacity under a peak power …

… Furthermore, the impact of imperfect channel knowledge on linear JD and linear JT is
compared. For simplicity, we concentrate on linear zero-forcing (ZF) JD [4] and linear ZF JT [16]–[18…

… Thus the analysis for imperfect channel knowledge will be very beneficial for the design
of … equation is used to reflect the impact of imperfections of the channel state information [7], …

… these works is that the channel state information (CSI… channel estimation errors, and more
importantly, channel feedback delay. In this paper, we focus on the case where only imperfect (…

… channels with imperfect channel knowledge. With random Gaussian inputs, the conventional
interference alignment (IA) method has the feasibility problem when the channel is quasi-…

… It should be noted that other receiver structures which take into account imprecise channel
knowledge have been reported in literature [7], [8], [17]–[20]. However, unlike the GLRD, they …

… the effect of imperfect knowledge of the transmission channel on the performance of … channel
is caused either by errors in the estimate of the channel or by variations in the channel due …
