| 摘 要： | 为了对无线信道的信号进行分离和对系统鲁棒性进行分析，文中把广义双曲线分布和小样本方法结合起来描述无线信道的状态。用MCMC方法来得到信道参数的满条件后验似然分布函数。对其采样来实现对信号的分离，同时用充分统计量对系统的鲁棒性进行分析。仿真结果表明．对于文中研究的模型，广义双曲线分布的假设是合理的。

| Abstract: | To the separation of the signal of wireless channel and the analysis of the robustness of system,the generalized hyperbolic distribution(GHD) model and DW method are presented in this paper to describe distribution characteristics of wireless channel state.The full condition of posterior distribution likelihood function is derived by using MCMC method.The separation of the signal is fulfilled by the samples drawn from the full condition distribution functions.In additional,the robustness of system is analyz... |
