9309044 Paris The Principal Investigator is addressing the estimation of the most likely state sequence of a discrete-time finite-state Markov process with unknown parameters observed in independent noise. A maximum likelihood criterion over both the input sequence and the parameters is introduced for estimating the state sequence without using an embedded training sequence. Asymptotically, this estimator is expected to be close to the maximum-likelihood sequence estimator with completely known parameters. To facilitate the search for the most likely state sequence, the investigator is introducing computationally simple algorithms which are guaranteed to converge. Besides developing the underlying theory and algorithms, the research is focussing on applications to digital mobile radio communication systems. The award provides support for three years.

9309044巴黎首席调查员正在研究在独立噪声中观察到未知参数的离散时间有限状态马尔可夫过程的最可能状态序列的估计。引入了关于输入序列和参数的最大似然准则，用于在不使用嵌入训练序列的情况下估计状态序列。渐近地，这种估计量有望接近参数完全已知的最大似然序列估计量。为了便于搜索最可能的状态序列，调查者引入了计算简单的算法，这些算法保证收敛。除了发展基本的理论和算法，研究的重点是在数字移动无线电通信系统中的应用。该奖项提供为期三年的支持。
