MBD technology is capable of integrating all the information of the design and process technology into the product 3D model. But in the MBD mode, the complex product has massive information, and its structure is extremely complicated. Generally, the existing methods for complex product information modeling have some limitations. By considering that, this paper proposed an F-B-S-F-I framework model...
This paper describes an approach to providing more accurate estimates of current radio coverage and real-time monitoring of coverage changes over time, in the context of self-organizing networks (SON). Radio coverage probability models based on received signal strength (RSS) from base stations (BSs) in an outdoor environment are created. Clustering is used to partition the RSS space and a nonparametric...
An improvement to outdoor fingerprint location estimation based on clustering received signal strength (RSS) from base stations (BSs) is presented. The novel features that contribute to the greater accuracy are the use of deviations from the path loss model for each RSS component rather than the raw RSS for clustering; the accurate estimation of the cluster membership probability; the optimized trade-off...
To achieve high data rates and seamless coverage, radio access networks continue to increase in complexity, and the expenditure on operational tasks continues to rise to unprecedented levels. The development of Long Term Evolution (LTE) with Self-organizing network (SON) functions is being considered as an effective way to tackle these challenges. The paper describes an approach to model the coverage...
To achieve geographic load balancing for spectrum efficiency and respond to the environment changes, cooperative control has shown that the system performance can be improved with global optimization among different cells in the system level simulations. When a cooperative control scheme is applied in the physical network, coverage holes are concern of the network operators. In this paper, the radio...
