Iterative Deconvolution and Receiver-Function Estimation

Abstract We describe and apply an iterative, time-domain deconvolution ap-proach to receiver-function estimation and illustrate the reliability and advantages of the technique using synthetic- and observation-based xamples. The iterative tech-nique is commonly used in earthquake time-function studies and offers several ad-vantages in receiver-function analysis such as intuitively stripping the largest re-ceiver-function arrivals from the observed seismograms first and then the details; long-period stability by a pr ior i constructing the deconvolution as a sum of Gaussian pulses; and easy generalization to allow multiwaveform deconvolution for a single receiver-function estimate.
