In order to meet the requirement of dramatically growing mobile data, the operators improve their network by aggregating multiple carriers to increase the system capacity. Due to the limited availability of licensed spectrum, unlicensed spectrum with large amount of resources has attracted more and more world-wide interests recently. The Licensed Assisted Access (LAA) using LTE(-A) on unlicensed bands...
In LTE-Advanced downlink, multiuser (MU)-MIMO transmission with closed-loop precoding matrix indicator (PMI) selection and use of interference suppression ability of mobile station (MS) receiver are promising technologies to improve spectrum efficiency. In this paper, we investigate the throughput performance of a proposed MU-MIMO codebook that contains amplitude control information in addition to...
Aiming at the shortcomings of the information protection equipment at present, an information hiding and protection equipment is designed and implemented based on the whitening technology. The interference signal is used to whiten the leakage in order to hide and interfere with the emission information. Theoretical analysis and experimental results show that the device hides the emission information...
Due to the limited feedback amount, the codebook and feedback design is very important. In order to achieve better tradeoff between overhead and performance, the double codebook structures are proposed and discussed, where a final precoder W is determined by two precoders W1 and W2, which are selected from two different codebooks. In this paper, we give an overview of several double codebook structures...
Mixed infections of Nicotiana benthamiana plants by Tobacco necrosis virus (TNV) and Turnip crinkle virus (TCV) exhibited an interference interaction. Accumulation of TNV (+)RNA as well as capsid protein in mixed infection were considerably lower than that of singly infected plants. There were also a slight reduction in the levels of TCV (+)RNA and capsid protein in doubly infected plants, which displayed...
