统计力学中相变参数估计中的阈值效应
Threshold effects in parameter estimation as phase transitions in statistical mechanics
摘要:
从统计物理学的角度研究了非线性调制、连续时间、宽带波形参数估计中的阈值效应。这些阈值效应被证明是类似于在热平衡的某些无序的物理系统的相变。在这项工作中,主要的信息是证明,这种物理的观点可能是有见地的理解两个或多个参数之间的相互作用估计,从阈值效应的方面。
英文摘要:
Threshold effects in the estimation of parameters of non-linearly modulated, continuous-time, wide-band waveforms, are examined from a statistical physics perspective. These threshold effects are shown to be analogous to phase transitions of certain disordered physical systems in thermal equilibrium. The main message, in this work, is in demonstrating that this physical point of view may be insightful for understanding the interactions between two or more parameters to be estimated, from the aspects of the threshold effect.
