Iterative Frequency Domain Combining Equalization Algorithm for Single Carrier Systems

  • 摘要: 为提高符号间干扰(ISI)信道条件下信号接收的可靠性,该文研究单载波通信系统的多天线空间分集接收问题,提出一种迭代频域合成均衡算法。该算法推导先验信息条件下合成均衡器的频域传输函数,并借助快速傅里叶变换(FFT)实现合成均衡器系数和均衡滤波的高效计算。仿真结果表明,相比时域算法,该算法能够在不损失性能的前提下,大幅降低运算复杂度。与单载波频域均衡(SC-FDE)算法相比,该算法不需要在数据传输的结构中插入循环前缀(CP),提高频谱利用率,能够直接应用于现有单载波通信系统。
