Efficient blind deconvolution of audio-frequency signal
James Norbert Caron, Forbes Boulevard · 2004
A signal processing algorithm has been developed in which a filter function is extracted fromdegradeddata throughmathematical operations. The filter function can be used to restore much of the degraded content of the data through use of a deconvolution process. The operation can be performed without prior knowledge of the detection system, a technique known as blind deconvolution. The extraction process, designated Selfdeconvolving Data Reconstruction Algorithm (SeDDaRA), is applied here to audio-frequency signals showing significant qualitative improvement. Degradation arising from the process of electronic recording and reproduction is significantly reduced.
