Bounds on inter-carrier interference power of OFDM in a Gaussian scattering channel

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 , ? frequency tracking and e mobile travelling direction. Insightful discussions on the characteristics of P ICI are given. Future work is also outlined.
