Under abnormal conditions, signals would propagate in the ducting layers with little attenuation. According to 3GPP, TD-LTE networks apply ICIC(Inter Cell Interference Cancellation Coordination) technology to solve co-channel interference problem.
Moreover, ADI severely impacts the performance of TD-LTE networks.

Moreover, they experience less attenuation in the ducts than they would if the ducts were not present. Because of the positions of actual BSs, after the rasterizing, some elements of matrix X may have no data. It is considered to be one of the best classification algorithms. In addition, we proposed an SVM (Support Vector Machine)-classifier based spacial prediction method of ADI by machine learning over combination of real network-side big data and real meteorological data. at Yevgeni is a co-founder and chairman of the Board of Finnish company YL-verkot Oy offering leading innovative technological solutions in 5G and Industrial IIoT domains. More detailed meteorological data is therefore a key factor in ADI time varying prediction.Investigation of surface duct conditions over Istanbul,TurkeyRadar detection of low-altitude targets in a maritime environmentRefractivity-from-clutter using global environmental parametersThe effect of atmospheric duct on modern OFDM-based digital broadcasting systemsDesign of an ocean atmospheric duct signal processor3GPP Technical Specification Group Radio Access Network; Evolved Universal Terrestrial Radio Access (EUTRA); Physical Channels and Modulations (Release 8).3GPP TS 36.213 version 8.8.0Interference rejection in digital wireless communicationsPower control based time-domain inter-cell interference coordination scheme in DSCNsOFDM channel estimation in the presence of interferenceCo-channel interference cancellation in reuse-1 deployments of WiMAX systemCo-channel interference cancellation based on SIC with optimal ordering for cooperative communication systemsPath loss exponent estimation for wireless sensor network localizationInterpolation of spatial data: some theory for krigingSequential minimal optimization: a fast algorithm for training support vector machinesDistributed optimization and statistical learning via the alternating direction method of multipliers Effects Prediction System (EREPS) Surface Duct Summary (SDS) database, on a world average, the evaporation duct height is approximately 13.1 m and evaporation ducts occur between 6-20 m at 72% of the time. The next step is to use interpolation to increase the resolution of the data.
Furthermore, an implementation of ADMM (Alternating Direction Methods of Multipliers) framework is proposed to implement a distributed SVM prediction scheme, which reduces data exchange among different regions/cities, maintains similar prediction accuracy and is thus of a more practical use to operators. Providing a professional service with competitive rates in all aspects of extraction units including the following: Prior to that, he has served the Department of Global Telecom Solutions Sector at MOTOROLA (China) co. , LTD, as a R＆D Senior Engineer; and the Department of Production Quality at Shanghai Datang Telcom, China, as a R＆D Engineer. This is denoted by atmospheric duct interference, i. e. ADI. The interference model defined here and based on SINR depends not only on antenna parameters (frequency, tilt, azimuth…) but also on traffic load along day; then in our computation the users available in target sector or adjacent sectors can affect the received signal from other users.
