| 摘 要： | 为了提高通信系统性能,采用粒子滤波方法对单载波频域均衡系统（SC-FDE）进行信道估计.文中阐述了单载波频域均衡系统及粒子滤波原理.在此基础之上,将粒子滤波的方法应用到单载波频域均衡系统的信道估计中去,并且给出应用步骤.由于该方法不用添加训练序列,因此提高了传输效率,降低了系统开销.最后,将粒子滤波方法和已有信道估计方法进行仿真对比,验证提出算法的优越性.

| Abstract: | The particle filter algorithm is applied to channel estimate of single carrier frequency domain equalization(SC-FDE) in order to improve the performance of communication system.Firstly,the generic ideas of SC-FDE system and particle filter theory are given.Secondly,based on this above mentioned,the particle filter algorithm is applied to channel estimate of SC-FDE system.Moreover,application steps are given too.Because this method does not need to add training sequence,it improves transmission efficiency an... |
