| 摘 要： | 针对高速率信息传输系统中多径衰落对单载波频域均衡(SC-FDE)信道估计造成的影响,在SC-FDE原理基础上,将无线通信中信噪比估计和SC-FDE中信道估计结合起来,对现有信噪比估计算法进行优化。分析和仿真结果表明,此方法能有效地改善多径衰落信道中信道估计的有效性,提高了频域均衡的效果,从而改善了SC-FDE系统的误码率(BER)性能。

| Abstract: | In broadband wireless communication system,multipath fading affects the performance of channel estimation.In order to improve the precision of channel-estimation,a new method which combines Signal-to-Noise with channel-estimation in SC-FDE is proposed in this paper.The MMSE algorithm is used to estimate the channel information.The analysis and simulation results demonstrate that the method can improve the effectiveness of channel estimation in multipath fading channel and enhance the effect of frequency domain equalization,and thus improve the performance of bit error rate(BER)of SC-FDE system. |
