Bounds on Inter-carrier Interference Power of OFDM in a Gaussian Scattering Channel

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