Abstract：The research on indoor terahertz wireless channel model is one of the hot topics in the field of wireless communications. With the rapid development of Internet of Things,5G and future communication technologies,the terahertz frequency band has attracted widespread attention due to its potential of large bandwidth and high data transmission rates. The current research status of indoor terahertz wireless channel models and modeling methods are reviewed. Firstly,the terahertz channel propagation characteristics such as terahertz spectrum characteristics and large-and small-scale fading are introduced. Secondly,the research status of key parameters such as path loss,Channel Impulse Response(CIR)/Channel Transfer Function(CTF),Power Delay Profile(PDP),Delay Spread(DS),Time of Arrival(ToA),Angular Spread(AS),and Angle of Arrival(AoA)in terahertz channel are sorted out,based on which the channel modeling methods are summarized into three categories,namely deterministic channel modeling,statistical channel modeling,and hybrid channel modeling. For each modeling method,the advantages and current status of existing related research lines are analyzed. Finally,the future development of terahertz wireless channel modeling is prospected.
