The DL CSI is usually measured at mobile stations (MSs) through DL training and fed back to the BS in frequency division duplexing (FDD). The DL training and uplink (UL) feedback might become infeasible due to insufficient coherence time interval when the channel rapidly changes due to high speed of MSs. Without the feedback from MSs, it may be possible for the BS to directly obtain the DL CSI using the inherent relation of UL and DL channels even in FDD, which is called DL extrapolation. Although the exact relation would be highly nonlinear, previous studies have shown that a neural network (NN) can be used to estimate the DL CSI from the UL CSI at the BS. Most of previous works on this line of research trained the NN using full dimensional UL and DL channels; however, the NN training complexity becomes severe as the number of antennas at the BS increases. To reduce the NN training complexity and improve DL CSI estimation quality, this paper proposes a path gain extraction technique to simplify the input and output of the NN. It is shown through many measurement campagines that the UL and DL channels still share common components like path delays and angles in FDD. The proposed technique first extracts these common coefficients from the UL and DL channels and trains the NN only using remaining components with reduced dimensions compared to the full UL and DL channels. Extensive simulation results show that the proposed technique outperforms the conventional approach, which relies on the full UL and DL channels to train the NN, regardless of the speed of MSs

Purpose: To compare the survival of corneal grafts and the changes in endothelial cell density in penetrating keratoplasty using domestic or imported corneas. Methods: Medical records of 236 eyes of 211 patients who underwent penetrating keratoplasty from November 2004 to August 2011 in Seoul National University Hospital and were followedup at least 1 year were retrospectively reviewed. After excluding the patients who received the combined surgeries with other surgeries except cataract surgery, the eyes were divided into 2 groups depending on the origin of donor tissue resulting in a domestic cornea group (108 eyes) and an imported cornea group (128 eyes). Recipient demographics, preoperative diagnosis, donor age, death-to-preservation time, death-to-operation time and pre-and postoperative visual acuities were compared between the 2 groups. Kaplan-Meier survival and changes in endothelial cell density were analyzed at 3, 6 and 12 months and then every year. Results: The most common preoperative diagnoses were regraft and corneal opacity in the domestic and imported cornea groups, respectively, without statistical difference. Death-to-preservation time was 8.9 hours and 8.0 hours in the domestic and imported cornea groups, respectively, without statistical difference. However, death-to-operation time was longer in the imported cornea group (4.98 days) than in the domestic cornea group (2.18 days). There were no differences in pre- and postoperative visual acuities, decrease in annual changes in endothelial densities and survival up to 3 years between the 2 groups. In addition, the survival and decreased annual changes in endothelial densities were not different from each other in penetrating keratoplasty combined with cataract surgery or in penetrating keratoplasty for a corneal edema. Conclusions: Our study results suggest that clinical outcomes of the penetrating keratoplasty using imported corneas are comparable in efficacy when compared with the clinical outcomes using domestic corneas.N
