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.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 and reduces system overhead.Finally,the particle filter algorithm and channel estimate algorithm are simulated and contrasted,verifying superiority of the proposed algorithm.
