摘要
采用噪声预测的单载波频域均衡结构,按照Turbo均衡的思想,提出了一种对噪声预测过程进行迭代的迭代单载波频域均衡的方法,并且分析设计了系统迭代均衡时的关键参数。仿真结果表明:基于迭代思想的噪声预测的单载波频域均衡系统在频率选择性衰落信道下具有良好的误比特性能,并且具有较低的复杂度。
In accordance with the idea of Turbo equalization and the structure of single-carrier frequency domain equalization with time domain noise prediction, an iterative single-carrier frequency domain equalization with time domain noise prediction system is proposed, and the key parameters of the system are analyzed and designed.Simulation results show that the iterative single-carrier frequency domain equalization with time domain noise prediction system has a good BER performance in frequency selective fading channel,and it has a lower complexity.
