Mechanisms about radio wave propagation are the basis for the research of wireless channel modeling. Typical wireless channel models for typical scenarios are of great importance to the physical layer techniques such as synchronization, channel estimation, and equalization. Nowadays, many channel models concerned with either large-scale modeling or small-scale fast fading models have been established. However, with the development of some new techniques such as multiuser MIMO systems, vehicle-to-vehicle technique, wireless relay technique, short distance or short range technique, and novel wireless channel models should be developed to cater for these new conditions.

Researchers are cordially invited to contribute original research articles that will stimulate the continuing efforts to understand the mechanisms about radio wave propagations and wireless channel models under variant scenarios and cater for the appearance of novel techniques. We are particularly interested in articles describing novel wireless channel models. Potential topics include, but are not limited to:

• Radio wave propagation mechanisms under high frequency band above 10GHz
• Radio wave propagation mechanisms under high speed railway scenarios
• Radio wave propagation mechanisms for ultrawideband systems
• Climate impacts such as cloud, rain, and fog on radio wave propagation
• Wireless channel measuring schemes for broadband communications systems
• OTA measurements for multiantenna systems
• Techniques about channel sounder
• Ray tracing techniques
• Satellite communications channel modeling
• THz communications channel modeling
• MIMO-UWB wireless channel modeling
• Propagation and channel modeling for cellular/LTE system
• Multiuser MIMO channel modeling
• Relay channel modeling
• Short distance or short range communications channel modeling
• Broadcasting channel modeling
• Wireless sensor networks channel modeling
• Vehicle-to-vehicle channel modeling
• Train-to-train channel modeling
• Body centric channel modeling
• Wireless body area networks channel modeling
• Modeling methods for wireless channel
