    Survey of application of machine learning in wireless channel modeling by Liu LIU, Jianhua ZHANG, Yuanyuan FAN, Li YU, Jiachi ZHANG

    Published 2021-02-01
    “…Channel characterization is primary to the design of the wireless communication system.The conventional channel characterization method cannot learn the law of certain types of channels by itself, which limits its application in several special scenarios, such as Internet of things, millimeter wave communication and Internet of vehicles.Machine learning was able to process the big data and establish the model.Based on this, the cooperation between the machine learning and channel characterization was investigated.The channel multipath clustering, parameter estimation, model construction and wireless channel scene recognition were discussed, and recent significant research results in this field were provided.Finally, the future direction of the machine learning in wireless channel modeling was proposed.…”

    Path Loss Modeling of Wireless Signals in Underground Tunnels by Yaning Li, Baoguo Yu, Lu Huang

    Published 2025-01-01
    “…Typical features of underground tunnels (sidewall roughness, metal conductors, tunnel inclinations, etc.) significantly affect signal propagation, making it difficult for a single modeling approach to accurately describe the field strength attenuation of a wireless channel in an underground tunnel. In this paper, a hybrid model describing the propagation attenuation of wireless signals in underground tunnels is proposed, which divides the propagation channel into three subdomains according to the length of the tunnel, namely, the region of the free space propagation model, the region of the multimode propagation described by the ray tracing method, and the region of the improved waveguide model by adding the influences of tunnel roughness, tunnel inclination, and metal pipes. …”

    An overview of low resolution quantization in wireless communication system by Dan QIAO, Chaokai WEN, Feifei GAO, Shi JIN

    Published 2017-06-01
    “…Compared to the 4th generation (4G) mobile communication technology,the 5th generation (5G) mobile communication technology will provide tens of times of peak rate increase,reaching up to several thousands megabit per second.The coming wireless communication systems face the problems of expensive hardware cost and high power consumption,which is becoming a bottleneck of high-rate communication systems.To cope with these problems,redesigning communication systems with the receiver using finite precision analog-to-digital converters (ADC) is one possible approach.The analysis of recent information theory for the AWGN channel shows that the performance loss due to 2~3 bit ADC acceptable.The application of low resolution quantization in wireless communication systems was focused on,an overview of the channel capacity and receiver design under low-precision ADC was provided.…”

    Optimal Pricing of Spectrum Resources in Wireless Opportunistic Access by Hanna Bogucka

    Published 2012-01-01
    “…We consider opportunistic access to spectrum resources in cognitive wireless networks. The users equipment, or the network nodes in general are able to sense the spectrum and adopt a subset of available resources (the spectrum and the power) individually and independently in a distributed manner, that is, based on their local channel quality information and not knowing the Channel State Information (CSI) of the other nodes' links in the considered network area. …”
