- Abstract
In this paper, we propose an adaptive inter-carrier interference (ICI) mitigation algorithm based on phase rotated conjugate cancellation (PRCC) scheme. For the MIMO-OFDM systems in high-speed train (HST) environment, the ICI is caused by the non-stationary time-varying channels. By updating the optimal phases every two OFDM symbols, our method achieves additional optimal rotated phases applicable for HST wireless channels. Simulation results demonstrate that the carrier-to-interference ratio (CIR) increase and the bit error rate (BER) decreases enormously in our method. Therefore, the proposed adaptive algorithm is effective for mitigating the ICI in HST environment comparing with the traditional ICI self-cancellation algorithm.
