Inter-carrier interference power of OFDM in a uniform scattering channel

This letter derives the upper and lower bounds on inter-carrier interference (ICI) power PICIPICI of OFDM in a uniform scattering channel. The bounds are computed as functions of fdTsfdTs product of the maximum Doppler spread fdfd and symbol duration Ts,ζTs,ζ frequency tracking and ϵϵ mobile travelling direction. Insightful discussions on the characteristics of PICIPICI are given. Future work is also outlined.
