| 摘 要： | 针对先进的长期演进(long term evolution advanced,LTE-Advanced)上行链路多输入多输出(multiple-input multiple-output,MIMO)单载波频分多址(single carrier frequency division multiple access,SC-FDMA)系统载波频率偏移(carrier frequency offset,CFO)的影响,提出了基于多级迭代干扰消除检测算法.将传统的单级串行干扰消除(successive interference cancellation,SIC)和并行干扰消除(parallel interference cancellation,PIC)进行混合迭代形成多级的迭代干扰消除检测算法以降低MIMO SC-FDMA系统的误比特率.理论分析和仿真结果表明两级PIC迭代检测算法和SIC+ PIC混合迭代检测算法都能实现MIMO SC-FDMA系统CFO干扰消除的目的,降低了MIMO SC-FDMA系统的误比特率,提高了系统的性能.

| Abstract: | Aiming at the carrier frequency offset''s (CFO) influence upon LTE-Advanced multiple-input multiple-output single carrier frequency division multiple access(MIMO SC-FDMA) uplink system, the detection algorithm based on multi-stage interference cancellation is proposed. It mixed the traditional single-stage successive interference cancellation(SIC) and parallel interference cancellation(PIC) to form multi-stage iteration interference cancellation algorithm, in order to decrease the bit error rate of multiple-input multiple-output single carrier frequency division multiple access(MIMO SC-FDMA) system.Theoretical analysis and simulation results show that the algorithm both two-stage-PIC and SIC+PIC has achieved the goal of CFO interference cancellation in the MIMO SC-FDMA system. |
