摘要 提出了一种消除载波频偏引起的多用户接入干扰的LMMSE-PIC算法。首先,采用线性最小均方误差(LMMSE)来估计各用户的频偏干扰,然后根据这些估计值采用一种迭代的并行干扰消除(PIC)算法来消除多用户接入干扰。仿真结果表明,所采用的算法对载波频偏的估计精度较高,消除MUI干扰的效果明显。 A Linear Minimum Mean Square Error Parallel Interference Cance scheme was proposed to cancel Multiple Access Interference （MUI） in uplink Division Multiple Access （OFDMA）. First, the Linear Minimum Mean Sq algorithm was derived to estimate the MUI. Then, the advantage of an iterati Cancellation （PIC） method was taken to cancel the MUI. Simulation improvements that can be obtained from the proposed suppression schemes. llation （LMMSE-PIC） Orthogonal Frequencyuare Error （LMMSE） ve Parallel Interference results illustrate the
