| 中文摘要 | 采用部分更新最小均方(LMS)算法和重叠保留的块信号频域处理结构,针对现场可编程门阵列(FPGA)的硬件实现平台,提出了时频混合部分更新块LMS和周期性块部分更新LMS均衡算法结构。2种新结构均能有效降低均衡算法的实现复杂度。步长收敛条件分析和数值仿真结果表明,新结构能够在适当调整更新步长的情况下,有效跟踪缓变信道的变化,实现与完整块LMS算法相当的性能,能够有效解决高速数据传输中的均衡复杂度过高的问题。; By adopting partial update Least Mean Square(LMS) algorithm and block processing structure featured with over-lapping and saving frequency domain, a hybrid time-frequency partial update block LMS equalization structure and periodic block partial update LMS equalization structure are proposed for the Field Programmable Gate Array(FPGA) platform. Both the two new structures can effectively reduce the equalization computational complexity. Analysis of convergence condition of step-size and numerical simulation results show that the new structures can effectively track the slowly time varying channels with proper adjustment of the step-size and achieve comparable performance as the complete block LMS algorithm; and the problem of high computational complexity equalizer in high speed communication could be effectively solved. |
