Abstract
In OFDMA uplink, each user is affected by different frequency offsets, which destroy the orthogonality between subcarriers, introduce inter-carrier interference, and seriously lower the BER performance. So the inter-carrier interference cancellation is indispensable at the receiver. A soft interference cancellation method is proposed in this paper, which combines frequency offsets compensation with channel decoding, and exhibits good convergence performance.
