1. A method for determining a signal parameter based at least in part on one or more estimated values, the method comprising: receiving a signal; and using processing equipment for: transforming the signal based at least in part on a wavelet transform; generating a scalogram based at least in part on the transformed signal, wherein the scalogram comprises a region of one or more at least partially unresolved values; estimating one or more values in the region; determining a signal parameter based at least in part on the one or more estimated values; and outputting the determined signal parameter to an output device.
