The Service Process and Modeling of Radio Channel in Multi-rate Wireless Networks

In modern wireless networks, Adaptive Modulation and Coding (AMC) is one of effective technologies adopted in physical layer to overcome complex wireless channel and improve quality of service of system. In this paper, the relation between wireless channel service process and traffic flow and AMC adopted in physical layer are analyzed, the wireless channel service process is modeled; and an equivalent burstiness characteristic AMC wireless channel modeling method is proposed. The burstiness character of AMC wireless channel and the feasibility and effectiveness of the proposed modeling method are proved with numerical analyses.
