An improved Doppler diversity technique for OFDM systems in time-varying multipath fading channels

摘要

Inter-channel interference(ICI), which results in an irreducible error floor, can be utilized as a source of Doppler diversity for OFDM systems in time-varying multipath channels. The proposed technique can enhance diversity gain by a new criterion for ICI cancellation in addition to enable the reduction of computational complexity and total detection time.
