| 摘 要： | 在衰落信道下检测传输符号是序列蒙特卡罗方法在通信领域中的一个重要应用.由于在序列蒙特卡罗方法中重要函数的选择直接会影响系统性能,针对这一问题,提出了一种新的混合重要函数,较大幅度提高了衰落信道下传输符号的检测水平,仿真结果也证实了这种新检测器的有效性.

| Abstract: | It is an important application in the field of communication that symbols transmitted over a flat fading channel are detected by sequential Monte Carlo(SMC) method. Because the choice of the importance function in SMC method has an effect on system performance, a new symbol detector is presented in this paper. The computer simulation results illustrate that this new detector can greatly improve the detection performance of the flat-fading channel. |
