We consider performance optimization of multi-cell networks with LTE and Wi-Fi aggregation (LWA) and LTE-unlicensed (LTE-U) with sharing of the unlicensed band. Theoretical results are derived to enable an algorithm to approach the optimum. Numerical results show the algorithm's effectiveness and benefits of joint use of LWA and LTE-U.

We investigate the effect of bursty traffic in an Long Term Evolution (LTE) and Wi-Fi aggregation (LWA)-enabled network. The LTE base station (BS) routes packets of the same IP flow through the LTE and Wi-Fi links independently. We motivate the use of superposition coding at the LWA-mode Wi- Fi access point (AP), so that it can serve LWA users and...

We investigate the effect of bursty traffic in an LTE and Wi-Fi aggregation (LWA)-enabled network, where part of the LTE traffic is offloaded to Wi-Fi access points (APs) to boost the performance of LTE networks. A Wi-Fi AP maintains two queues containing data intended for the LWA-mode user and the native Wi-Fi user, and it is allowed to serve them...

For unlicensed spectrum utilization in cellular networks, most of the existing efforts have addressed separately Wi-Fi offloading or LTE-unlicensed (LTE-U) with sharing of unlicensed bands occupied by Wi-Fi. Compared to the single-cell case, optimization for joint Wi-Fi offloading and LTE-U in multi-cell scenarios poses more challenges because inte...

Long Term Evolution (LTE)-Wireless Local Area Network (WLAN) Path Aggregation (LWPA) based on Multi-path Transmission Control Protocol (MPTCP) has been under standardization procedure as a promising and cost-efficient solution to boost Downlink (DL) data rate and handle the rapidly increasing data traffic. This paper aims at providing tractable ana...

Licensed-assisted access (LAA) is a promising technology to meet the exponential increase of traffic demand by exploiting the 5GHz unlicensed spectrum. However, without proper coexistence schemes, the performance of WiFi in coexistence with LAA will be degraded significantly. Equipped with listen-before-talk (LBT) schemes, LAA applies a channel acc...
Conference Paper
In order to solver the high frequency (HF) skywave signal field intensity data influenced by ionosphere fast fading, the gross error discriminant formula based on GM(1,1) is used to eliminate the break data influenced by the ionosphere fast fading in this paper. By introducing modeling accuracy and distinguish threshold, the gross error discriminan...
Conference Paper
The diffuse reflection type of omni-directional laser warning based on fish-eye lens is becoming more and more important. As one of the key parameters of warning system, the warning radius should be put into investigation emphatically. The paper firstly theoretically analyzes the energy detected by single pixel of FPA detector in the system under c...
Conference Paper
GM (1, 1) is a biased grey exponential model, whose accuracy depends on the structure of background values and the selection of original conditions. Current literatures optimized GM (1, 1) models just by optimizing background values or original conditions separately, or by combining them jointly. However, these methods all ignored the accumulative...
Conference Paper
Radar cross section is an extremely important parameter in narrowband radar application for space target detection, tracking, and identification, as well as for the purpose of threat assessment. An analysis algorism, together with related software for measured RCS data has been developed to extract information from the original data. Some analyzing...

Aiming at the gross error detection problem of small samples whose distribution is unknown, two novel detection approaches based on GM(1,1) model, direct modeling detection approach and extrapolated precision detection approach were proposed. Firstly, the mechanism of GM(1,1) and the correlative modeling parameters were introduced. Secondly, the de...
