Abstract

This letter derives the upper and lower bounds on inter-carrier interference power P ICI of Orthogonal Frequency Division Multiplexing (OFDM) in a Gaussian scattering channel. The bounds are computed as functions of f d T s product of the maximum Doppler spread f d and symbol duration T s , 驴 frequency tracking and 驴 mobile travelling direction. Insightful discussions on the characteristics of P ICI are given. Future work is also outlined.
