将Rissanen的MDL原理应用于随机信号模型的选择，提出了一种检测相干和非相干信号的新方法。该方法将检测和定位同时进行，定位估计量与Bohme导出的极大似然估计量一致。该方法优于最近提出的Wax和Ziskind方法，特别是在阈值区域。仿真结果证明了改进后的性能。
We present a novel method for the detection of coherent and noncoherent signals based on the application of Rissanen's MDL principle for model selection to the stochastic signals model. In this method the detection and localization are done simultaneously, with the location estimator coinciding with the maximum likelihood estimator derived by Bohme. The proposed method outperforms the recently proposed method of Wax and Ziskind, especially in the threshold region. Simulation results demonstrating the improved performance are included.
