| 摘要: |
| 本文探讨了仅已知噪声一维分布和二阶统计特性的条件下非高斯无穷相关噪声中确知弱信号的最佳检测问题。在假设噪声为一阶 AR过程ni=yi+pni-l 的情况下，以最优化检测器的渐近相对效验为准则。并对 ρ 取一阶和二阶近似的意义下，分别得到了最佳有记忆和无记忆检测器的闭式解。推证和比较了它们同非高斯白噪声中的最佳检测器在结构上的异同和性能上的改进程度。最后给出了几个典型的实际例子。 |

| Abstract: |
| In this paper optimum detection of the weak signal in the non-Gaussian dependent noise is discussed. Under the assumptions that the noise can be expressed as a first-order AR process ni=ρni-1+yi and only marginal distribution of noise samples and dependent coefficient ρare given，if ρ is small，the optimum strueture of memory and memoryless detectors can be respectively obtained by maxmizing the first-order and the seeond-order approximations of efficacy to ρ. |
