For high-speed mobility,especially in the context of high-speed railway,the channel characteristics under the condition of high-speed mobile are analyzed firstly,the article,based on the SC-FDE,proposes the reasonable design of frame structure against the fast time-varying channel effects,and add spatial diversity and frequency diversity to obtain diversity gain against fading further.Simulation results show that SC-FDE can effectively support diversity reception,solve the channel fast fading caused by high-speed mobility and improve communication quality in the high-speed mobile environment.
