摘要
This paper describes an ICI mitigation method based on the generalized data-allocation of (1, beta) for orthogonal frequency division multiplexing systems. To improve the performance of the ICI mitigation for the higher-frequency offset, we propose an efficient search algorithm to generate the sub-optimal parameter beta for maximizing the carrier-to-interference ratio (CIR). The CIR and bit error rate performances of the proposed method were derived in this paper. The performances with different carrier frequency offset scenarios were evaluated by computer simulations. According to the simulation results, the performance of the proposed ICI mitigation scheme is better than that of the conventional ICI self-cancellation scheme and is nearly the same as that of the ICI self-cancellation scheme for the optimal parameter beta. Additionally, the proposed ICI mitigation scheme has a dramatically reduced hardware complexity in comparison with the ICI self-cancellation scheme for the optimal parameter beta.
