SUMMARY AND FUTURE DIRECTIONS

• We demonstrated four estimators of the linear frequency chirp parameter $\alpha$ that may be used to enhance sinusoidal modeling.
• The estimators apply to Hann windowed signals, which are often found in COLA systems (as opposed to Gaussian windowed signals).
• The estimators yield $\alpha$ estimates accurate to within 2%, though the inexact nature of our models still leads to observable distance from the Cramèr-Rao lower bound.
• Future work will compare the current estimators to estimators for Gaussian windowed signals, and will detail implementation of the current estimators as a single-output estimator.
