In practical asynchronous physical-layer network coding (PNC) systems, the symbols from multiple transmitters to a common receiver may be misaligned. The good performance of an asynchronous PNC decoder hinges on accurate estimation of the symbol misalignment. This paper puts forth an optimal symbol misalignment estimator that considerably improves the estimation accuracy over prior schemes. Our scheme...
We design non-codebook-based Multiple-Input Multiple-Output (MIMO) precoding schemes using multiple cell-specific reference signals patterns for the time division duplex (TDD) mode of LTE, where channel reciprocity can be exploited. Previously proposed non-codebook-based precoding schemes typically use UE specific reference signals for demodulation. Cell specific reference signals are however always...
According to the issues of the fourth party logistics platform usability, this paper analyzes the usability factors which influenced the platform from the perspective of third party logistics member and consignable company, and the evaluation index system of fourth party logistics platform usability was determined according to the designing, analysis and correction of questionnaire. And this paper...
Numerous studies have shown that the myocilin gene (MYOC) plays an important role in primary open-angle glaucoma (POAG) and high myopia. However, little is known about the genetic regulatory network. In this study, we combined array analysis and quantitative trait loci (QTL) mapping approaches (genetical genomics) to characterize the expression variation and the regulatory network of Myoc in the eye...
In this paper, we propose a novel codebook-based precoding design for orthogonal space-time block codes (OSTBCs) over multiple-input multiple-output (MIMO) channels with finite rate feedback. The proposed approach aims at providing better system performance by utilizing the property of OSTBCs and the prior information of the statistical antenna correlation. Under a new way of controlling the average...
