Abstract

This letter derives the upper and lower bounds on inter-carrier interference (ICI) power P"I"C"I of OFDM in a uniform scattering channel. The bounds are computed as functions of f"dT"s product of the maximum Doppler spread f"d and symbol duration T"s,@z frequency tracking and @e mobile travelling direction. Insightful discussions on the characteristics of P"I"C"I are given. Future work is also outlined.
