Estimating Transform Values Using Signal Estimates
First Claim
1. A method for estimating transform values using a signal estimate comprising:
- obtaining a first portion of a biological signal from a sensor;
estimating a second portion of the signal based at least in part on the first portion of the signal;
performing a transform of the signal based at least in part on the first portion of the signal and the second portion of the signal; and
determining a biological parameter corresponding to the signal based at least in part on the transformed signal.

Abstract
According to embodiments, estimated values for a signal transform may be generated using estimated values for the signal. Signal parameters may then be determined based on the estimated signal transform. A first portion of a signal may be obtained. A second portion of the signal may be estimated. The second portion of the signal may correspond to a portion of the that is unknown, that is not yet available and/or that is obscured by noise and/or artifacts. A transform (e.g., a continuous wavelet transform) of both of the signal portions may be performed. One or more parameters corresponding to the signal may then be determined from transformed signal.
