CAREER: Signal Processing for Auditory System Investigations

0447705 Ziarani拟议的研究和教育活动的重点是开发新的信号分析算法，这些算法将具有普遍的应用，在拟议的计划中，它们将用于研究听觉系统的功能。具体而言，申请人计划开发用于调查两种类型的听觉测试的信号分析技术，即耳声发射（OAE）和听觉诱发电位（AEP）。在信号分析中，这是一个时频问题。PI先前开发了一种新的算法，该算法允许确定给定信号中单个正弦分量随时间的振幅、频率和相位变化。在拟议的研究中，计划是扩展该算法，以跟踪多个正弦波，因为它们随着时间的推移而演变。两个拓扑结构的扩展算法被认为是和理论上的讨论提供了可能的解决方案。

0447705ZiaraniThe proposed research and educational activities have a focus on development of novel signal analysis algorithms that will have general application, in the proposed plan, they will be used to investigate the function of auditory system. Specifically, the applicant plans to develop signal analysis techniques for investigation of two types of auditory testing, the otoacoustic emissions (OAE) and Auditory Evoked Potentials (AEP). In a signal analysis context, this is a time-frequency problem. The PI has previously developed a novel algorithm that permits determination of changes in amplitude, frequency and phase over time of a single sinusoidal component from a given signal. In the proposed research, the plan is to extend this algorithm to track multiple sinusoids as they evolve with time. Two topographies of the extension algorithm are considered and theoretical discussion regarding possible approaches to the solution are provided.
